Remove `service_name` from `TaskExecutor`
Co-Authored-By: Abhivansh <31abhivanshj@gmail.com>
There are certain crates which we re-export within `types` which creates a fragmented DevEx, where there are various ways to import the same crates.
```rust
// consensus/types/src/lib.rs
pub use bls::{
AggregatePublicKey, AggregateSignature, Error as BlsError, Keypair, PUBLIC_KEY_BYTES_LEN,
PublicKey, PublicKeyBytes, SIGNATURE_BYTES_LEN, SecretKey, Signature, SignatureBytes,
get_withdrawal_credentials,
};
pub use context_deserialize::{ContextDeserialize, context_deserialize};
pub use fixed_bytes::FixedBytesExtended;
pub use milhouse::{self, List, Vector};
pub use ssz_types::{BitList, BitVector, FixedVector, VariableList, typenum, typenum::Unsigned};
pub use superstruct::superstruct;
```
This PR removes these re-exports and makes it explicit that these types are imported from a non-`consensus/types` crate.

While the Lighthouse implementation of the `ValidatorStore` does not really care about blobs, Anchor needs to be able to return different blobs from `sign_blocks` than what was passed into it, in case it decides to sign another Anchor node's block. Only passing the unsigned block into `sign_block` and only returning a signed block from it (without any blobs and proofs) was an oversight in #6705.
- Replace `validator_store::{Uns,S}ignedBlock` with `validator_store::block_service::{Uns,S}ignedBlock`, as we need all data in there.
- In `lighthouse_validator_store`, just add the received blobs back to the signed block after signing it.
- Create trait `ValidatorStore` with all functions used by the `validator_services`
- Make `validator_services` generic on `S: ValidatorStore`
- Introduce `LighthouseValidatorStore`, which has identical functionality to the old `ValidatorStore`
- Remove dependencies (especially `environment`) from `validator_services` and `beacon_node_fallback` in order to be able to cleanly use them in Anchor

Attempting to improve our CI speeds as its recently been a pain point.
Major changes:
- Use a github action to pull stable/nightly rust rather than building it each run
- Shift test suite to `nexttest` https://github.com/nextest-rs/nextest for CI
UPDATE:
So I've iterated on some changes, and although I think its still not optimal I think this is a good base to start from. Some extra things in this PR:
- Shifted where we pull rust from. We're now using this thing: https://github.com/moonrepo/setup-rust . It's got some interesting cache's built in, but was not seeing the gains that Jimmy managed to get. In either case tho, it can pull rust, cargofmt, clippy, cargo nexttest all in < 5s. So I think it's worthwhile.
- I've grouped a few of the check-like tests into a single test called `code-test`. Although we were using github runners in parallel which may be faster, it just seems wasteful. There were like 4-5 tests, where we would pull lighthouse, compile it, then run an action, like clippy, cargo-audit or fmt. I've grouped these into a single action, so we only compile lighthouse once, then in each step we run the checks. This avoids compiling lighthouse like 5 times.
- Ive made doppelganger tests run on our local machines to avoid pulling foundry, building and making lcli which are all now baked into the images.
- We have sccache and do not incremental compile lighthouse
Misc bonus things:
- Cargo update
- Fix web3 signer openssl keys which is required after a cargo update
- Use mock_instant in an LRU cache test to avoid non-deterministic test
- Remove race condition in building web3signer tests
There's still some things we could improve on. Such as downloading the EF tests every run and the web3-signer binary, but I've left these to be out of scope of this PR. I think the above are meaningful improvements.

## Issue Addressed
Synchronize dependencies and edition on the workspace `Cargo.toml`
## Proposed Changes
with https://github.com/rust-lang/cargo/issues/8415 merged it's now possible to synchronize details on the workspace `Cargo.toml` like the metadata and dependencies.
By only having dependencies that are shared between multiple crates aligned on the workspace `Cargo.toml` it's easier to not miss duplicate versions of the same dependency and therefore ease on the compile times.
## Additional Info
this PR also removes the no longer required direct dependency of the `serde_derive` crate.
should be reviewed after https://github.com/sigp/lighthouse/pull/4639 get's merged.

Web3Signer now requires Java runtime v17, see [v23.8.0 release](https://github.com/Consensys/web3signer/releases/tag/23.8.0).
We have some Web3Signer tests that requires a compatible Java runtime to be installed on dev machines. This PR updates `setup` documentation in Lighthouse book, and also fixes a small typo.
## Issue Addressed
`web3signer_tests` can sometimes timeout.
## Proposed Changes
Increase the `web3signer_tests` timeout from 20s to 30s
## Additional Info
Previously I believed the consistent CI failures were due to this, but it ended up being something different. See below:
---
The timing of this makes it very likely it is related to the [latest release of `web3-signer`](https://github.com/Consensys/web3signer/releases/tag/23.8.1).
I now believe this is due to an out of date Java runtime on our runners. A newer version of Java became a requirement with the new `web3-signer` release.
However, I was getting timeouts locally, which implies that the margin before timeout is quite small at 20s so bumping it up to 30s could be a good idea regardless.
## Issue Addressed
updates underlying dependencies and removes the ignored `RUSTSEC`'s for `cargo audit`.
Also switches `procinfo` to `procfs` on `eth2` to remove the `nom` warning, `procinfo` is unmaintained see [here](https://github.com/danburkert/procinfo-rs/issues/46).
## Issue Addressed
Attempt to fix#3812
## Proposed Changes
Move web3signer binary download script out of build script to avoid downloading unless necessary. If this works, it should also reduce the build time for all jobs that runs compilation.
## Proposed Changes
Remove built-in support for Ropsten and Kiln via the `--network` flag. Both testnets are long dead and deprecated.
This shaves about 30MiB off the binary size, from 135MiB to 103MiB (maxperf), or 165MiB to 135MiB (release).
## Issue Addressed
https://github.com/sigp/lighthouse/issues/3091
Extends https://github.com/sigp/lighthouse/pull/3062, adding pre-bellatrix block support on blinded endpoints and allowing the normal proposal flow (local payload construction) on blinded endpoints. This resulted in better fallback logic because the VC will not have to switch endpoints on failure in the BN <> Builder API, the BN can just fallback immediately and without repeating block processing that it shouldn't need to. We can also keep VC fallback from the VC<>BN API's blinded endpoint to full endpoint.
## Proposed Changes
- Pre-bellatrix blocks on blinded endpoints
- Add a new `PayloadCache` to the execution layer
- Better fallback-from-builder logic
## Todos
- [x] Remove VC transition logic
- [x] Add logic to only enable builder flow after Merge transition finalization
- [x] Tests
- [x] Fix metrics
- [x] Rustdocs

## Issue Addressed
#3369
## Proposed Changes
The goal is to make it possible to build Lighthouse without network access,
so builds can be reproducible.
This parallels the existing functionality in `common/deposit_contract/build.rs`,
which allows specifying a filename through the environment to avoid downloading
it. In this case, by specifying the version and making it available on the
filesystem, the existing logic will avoid a network download.
## Issue Addressed
#3302
## Proposed Changes
Move the `reqwest::Client` from being initialized per-validator, to being initialized per distinct Web3Signer.
This is done by placing the `Client` into a `HashMap` keyed by the definition of the Web3Signer as specified by the `ValidatorDefintion`. This will allow multiple Web3Signers to be used with a single VC and also maintains backwards compatibility.
## Additional Info
This was done to reduce the memory used by the VC when connecting to a Web3Signer.
I set up a local testnet using [a custom script](https://github.com/macladson/lighthouse/tree/web3signer-local-test/scripts/local_testnet_web3signer) and ran a VC with 200 validator keys:
VC with Web3Signer:
- `unstable`: ~200MB
- With fix: ~50MB
VC with Local Signer:
- `unstable`: ~35MB
- With fix: ~35MB
> I'm seeing some fragmentation with the VC using the Web3Signer, but not when using a local signer (this is most likely due to making lots of http requests and dealing with lots of JSON objects). I tested the above using `MALLOC_ARENA_MAX=1` to try to reduce the fragmentation. Without it, the values are around +50MB for both `unstable` and the fix.
## Issue Addressed
Web3signer validators can't produce post-Bellatrix blocks.
## Proposed Changes
Add support for Bellatrix to web3signer validators.
## Additional Info
I am running validators with this code on Ropsten, but it may be a while for them to get a proposal.
## Issue Addressed
* #3173
## Proposed Changes
Moved all `fee_recipient_file` related logic inside the `ValidatorStore` as it makes more sense to have this all together there. I tested this with the validators I have on `mainnet-shadow-fork-5` and everything appeared to work well. Only technicality is that I can't get the method to return `401` when the authorization header is not specified (it returns `400` instead). Fixing this is probably quite difficult given that none of `warp`'s rejections have code `401`.. I don't really think this matters too much though as long as it fails.
## Issue Addressed
Lays the groundwork for builder API changes by implementing the beacon-API's new `register_validator` endpoint
## Proposed Changes
- Add a routine in the VC that runs on startup (re-try until success), once per epoch or whenever `suggested_fee_recipient` is updated, signing `ValidatorRegistrationData` and sending it to the BN.
- TODO: `gas_limit` config options https://github.com/ethereum/builder-specs/issues/17
- BN only sends VC registration data to builders on demand, but VC registration data *does update* the BN's prepare proposer cache and send an updated fcU to a local EE. This is necessary for fee recipient consistency between the blinded and full block flow in the event of fallback. Having the BN only send registration data to builders on demand gives feedback directly to the VC about relay status. Also, since the BN has no ability to sign these messages anyways (so couldn't refresh them if it wanted), and validator registration is independent of the BN head, I think this approach makes sense.
- Adds upcoming consensus spec changes for this PR https://github.com/ethereum/consensus-specs/pull/2884
- I initially applied the bit mask based on a configured application domain.. but I ended up just hard coding it here instead because that's how it's spec'd in the builder repo.
- Should application mask appear in the api?

## Issue Addressed
Web3Signer validators do not support client authentication. This means the `--tls-known-clients-file` option on Web3Signer can't be used with Lighthouse.
## Proposed Changes
Add two new fields to Web3Signer validators, `client_identity_path` and `client_identity_password`, which specify the path and password for a PKCS12 file containing a certificate and private key. If `client_identity_path` is present, use the certificate for SSL client authentication.
## Additional Info
I am successfully validating on Prater using client authentication with Web3Signer and client authentication.
## Proposed Changes
Lots of lint updates related to `flat_map`, `unwrap_or_else` and string patterns. I did a little more creative refactoring in the op pool, but otherwise followed Clippy's suggestions.
## Additional Info
We need this PR to unblock CI.
## Issue Addressed
NA
## Proposed Changes
This PR extends #3018 to address my review comments there and add automated integration tests with Geth (and other implementations, in the future).
I've also de-duplicated the "unused port" logic by creating an `common/unused_port` crate.
## Additional Info
I'm not sure if we want to merge this PR, or update #3018 and merge that. I don't mind, I'm primarily opening this PR to make sure CI works.

## Issue Addressed
#2883
## Proposed Changes
* Added `suggested-fee-recipient` & `suggested-fee-recipient-file` flags to validator client (similar to graffiti / graffiti-file implementation).
* Added proposer preparation service to VC, which sends the fee-recipient of all known validators to the BN via [/eth/v1/validator/prepare_beacon_proposer](https://github.com/ethereum/beacon-APIs/pull/178) api once per slot
* Added [/eth/v1/validator/prepare_beacon_proposer](https://github.com/ethereum/beacon-APIs/pull/178) api endpoint and preparation data caching
* Added cleanup routine to remove cached proposer preparations when not updated for 2 epochs
## Additional Info
Changed the Implementation following the discussion in #2883.

## Issue Addressed
Currently, running the Web3Signer tests locally without having a java runtime environment installed and available on your PATH will result in the tests failing.
## Proposed Changes
Add a note regarding the Web3Signer tests being dependent on java (similar to what we have for `ganache-cli`)
## Issue Addressed
e895074ba updated the altair fork and now that we are a week away this test no longer panics.
## Proposed Changes
Remove the expected panic and explanatory note.
[EIP-3030]: https://eips.ethereum.org/EIPS/eip-3030
[Web3Signer]: https://consensys.github.io/web3signer/web3signer-eth2.html
## Issue Addressed
Resolves#2498
## Proposed Changes
Allows the VC to call out to a [Web3Signer] remote signer to obtain signatures.
## Additional Info
### Making Signing Functions `async`
To allow remote signing, I needed to make all the signing functions `async`. This caused a bit of noise where I had to convert iterators into `for` loops.
In `duties_service.rs` there was a particularly tricky case where we couldn't hold a write-lock across an `await`, so I had to first take a read-lock, then grab a write-lock.
### Move Signing from Core Executor
Whilst implementing this feature, I noticed that we signing was happening on the core tokio executor. I suspect this was causing the executor to temporarily lock and occasionally trigger some HTTP timeouts (and potentially SQL pool timeouts, but I can't verify this). Since moving all signing into blocking tokio tasks, I noticed a distinct drop in the "atttestations_http_get" metric on a Prater node:

I think this graph indicates that freeing the core executor allows the VC to operate more smoothly.
### Refactor TaskExecutor
I noticed that the `TaskExecutor::spawn_blocking_handle` function would fail to spawn tasks if it were unable to obtain handles to some metrics (this can happen if the same metric is defined twice). It seemed that a more sensible approach would be to keep spawning tasks, but without metrics. To that end, I refactored the function so that it would still function without metrics. There are no other changes made.
## TODO
- [x] Restructure to support multiple signing methods.
- [x] Add calls to remote signer from VC.
- [x] Documentation
- [x] Test all endpoints
- [x] Test HTTPS certificate
- [x] Allow adding remote signer validators via the API
- [x] Add Altair support via [21.8.1-rc1](https://github.com/ConsenSys/web3signer/releases/tag/21.8.1-rc1)
- [x] Create issue to start using latest version of web3signer. (See #2570)
## Notes
- ~~Web3Signer doesn't yet support the Altair fork for Prater. See https://github.com/ConsenSys/web3signer/issues/423.~~
- ~~There is not yet a release of Web3Signer which supports Altair blocks. See https://github.com/ConsenSys/web3signer/issues/391.~~
