43c5e924d7 Add --semi-supernode support (#8254)
Addresses #8218

A simplified version of #8241 for the initial release.

I've tried to minimise the logic change in this PR, although introducing the `NodeCustodyType` enum still result in quite a bit a of diff, but the actual logic change in `CustodyContext` is quite small.

The main changes are in the `CustdoyContext` struct
* ~~combining `validator_custody_count` and `current_is_supernode` fields into a single `custody_group_count_at_head` field. We persist the cgc of the initial cli values into the `custody_group_count_at_head` field and only allow for increase (same behaviour as before).~~
* I noticed the above approach caused a backward compatibility issue, I've [made a fix](15569bc085) and changed the approach slightly (which was actually what I had originally in mind):
* when initialising, only override the  `validator_custody_count` value if either flag `--supernode` or `--semi-supernode` is used; otherwise leave it as the existing default `0`. Most other logic remains unchanged.

All existing validator custody unit tests are still all passing, and I've added additional tests to cover semi-supernode, and restoring `CustodyContext` from disk.

Note: I've added a `WARN` if the user attempts to switch to a `--semi-supernode` or `--supernode` - this currently has no effect, but once @eserilev column backfill is merged, we should be able to support this quite easily.

Things to test
- [x] cgc in metadata / enr
- [x] cgc in metrics
- [x] subscribed subnets
- [x] getBlobs endpoint

33e21634cb Custody backfill sync (#7907)
#7603


  #### Custody backfill sync service
Similar in many ways to the current backfill service. There may be ways to unify the two services. The difficulty there is that the current backfill service tightly couples blocks and their associated blobs/data columns. Any attempts to unify the two services should be left to a separate PR in my opinion.

#### `SyncNeworkContext`
`SyncNetworkContext` manages custody sync data columns by range requests separetly from other sync RPC requests. I think this is a nice separation considering that custody backfill is its own service.

#### Data column import logic
The import logic verifies KZG committments and that the data columns block root matches the block root in the nodes store before importing columns

#### New channel to send messages to `SyncManager`
Now external services can communicate with the `SyncManager`. In this PR this channel is used to trigger a custody sync. Alternatively we may be able to use the existing `mpsc` channel that the `SyncNetworkContext` uses to communicate with the `SyncManager`. I will spend some time reviewing this.

11bcccb353 Remove all prod eth1 related code (#7133)
N/A


  After the electra fork which includes EIP 6110, the beacon node no longer needs the eth1 bridging mechanism to include new deposits as they are provided by the EL as a `deposit_request`. So after electra + a transition period where the finalized bridge deposits pre-fork are included through the old mechanism, we no longer need the elaborate machinery we had to get deposit contract data from the execution layer.

Since holesky has already forked to electra and completed the transition period, this PR basically checks to see if removing all the eth1 related logic leads to any surprises.

5f208bb858 Implement basic validator custody framework (no backfill) (#7578)
Resolves #6767


  This PR implements a basic version of validator custody.
- It introduces a new `CustodyContext` object which contains info regarding number of validators attached to a node and  the custody count they contribute to the cgc.
- The `CustodyContext` is added in the da_checker and has methods for returning the current cgc and the number of columns to sample at head. Note that the logic for returning the cgc existed previously in the network globals.
- To estimate the number of validators attached, we use the `beacon_committee_subscriptions` endpoint. This might overestimate the number of validators actually publishing attestations from the node in the case of multi BN setups. We could also potentially use the `publish_attestations` endpoint to get a more conservative estimate at a later point.
- Anytime there's a change in the `custody_group_count` due to addition/removal of validators, the custody context should send an event on a broadcast channnel. The only subscriber for the channel exists in the network service which simply subscribes to more subnets. There can be additional subscribers in sync that will start a backfill once the cgc changes.

TODO

- [ ] **NOT REQUIRED:** Currently, the logic only handles an increase in validator count and does not handle a decrease. We should ideally unsubscribe from subnets when the cgc has decreased.
- [ ] **NOT REQUIRED:** Add a service in the `CustodyContext` that emits an event once `MIN_EPOCHS_FOR_BLOB_SIDECARS_REQUESTS ` passes after updating the current cgc. This event should be picked up by a subscriber which updates the enr and metadata.
- [x] Add more tests

70850fe58d Drop head tracker for summaries DAG (#6744)
The head tracker is a persisted piece of state that must be kept in sync with the fork-choice. It has been a source of pruning issues in the past, so we want to remove it
- see https://github.com/sigp/lighthouse/issues/1785

When implementing tree-states in the hot DB we have to change the pruning routine (more details below) so we want to do those changes first in isolation.
- see https://github.com/sigp/lighthouse/issues/6580
- If you want to see the full feature of tree-states hot https://github.com/dapplion/lighthouse/pull/39

Closes https://github.com/sigp/lighthouse/issues/1785


  **Current DB migration routine**

- Locate abandoned heads with head tracker
- Use a roots iterator to collect the ancestors of those heads can be pruned
- Delete those abandoned blocks / states
- Migrate the newly finalized chain to the freezer

In summary, it computes what it has to delete and keeps the rest. Then it migrates data to the freezer. If the abandoned forks routine has a bug it can break the freezer migration.

**Proposed migration routine (this PR)**

- Migrate the newly finalized chain to the freezer
- Load all state summaries from disk
- From those, just knowing the head and finalized block compute two sets: (1) descendants of finalized (2) newly finalized chain
- Iterate all summaries, if a summary does not belong to set (1) or (2), delete

This strategy is more sound as it just checks what's there in the hot DB, computes what it has to keep and deletes the rest. Because it does not rely and 3rd pieces of data we can drop the head tracker and pruning checkpoint. Since the DB migration happens **first** now, as long as the computation of the sets to keep is correct we won't have pruning issues.

2bd5bbdffb Optimise and refine SingleAttestation conversion (#6934)
Closes

- https://github.com/sigp/lighthouse/issues/6805


  - Use a new `WorkEvent::GossipAttestationToConvert` to handle the conversion from `SingleAttestation` to `Attestation` _on_ the beacon processor (prevents a Tokio thread being blocked).
- Improve the error handling for single attestations. I think previously we had no ability to reprocess single attestations for unknown blocks -- we would just error. This seemed to be the case in both gossip processing and processing of `SingleAttestation`s from the HTTP API.
- Move the `SingleAttestation -> Attestation` conversion function into `beacon_chain` so that it can return the `attestation_verification::Error` type, which has well-defined error handling and peer penalties. The now-unused variants of `types::Attestation::Error` have been removed.

c6ebaba892 Detect invalid proposer signature on RPC block processing (#6519)
Complements
- https://github.com/sigp/lighthouse/pull/6321

by detecting if the proposer signature is valid or not during RPC block processing. In lookup sync, if the invalid signature signature is the proposer signature, it's not deterministic on the block root. So we should only penalize the sending peer and retry. Otherwise, if it's on the body we should drop the lookup and penalize all peers that claim to have imported the block

## Issue Addressed
Addresses [#4401](https://github.com/sigp/lighthouse/issues/4401)

## Proposed Changes
Shift some constants into ```ChainSpec``` and remove the constant values from code space.

## Additional Info

I mostly used ```MainnetEthSpec::default_spec()``` for getting ```ChainSpec```. I wonder Did I make a mistake about that.

6c375205fb Fix HTTP state API bug and add --epochs-per-migration (#4236)
## Issue Addressed

Fix an issue observed by `@zlan` on Discord where Lighthouse would sometimes return this error when looking up states via the API:

> {"code":500,"message":"UNHANDLED_ERROR: ForkChoiceError(MissingProtoArrayBlock(0xc9cf1495421b6ef3215d82253b388d77321176a1dcef0db0e71a0cd0ffc8cdb7))","stacktraces":[]}

## Proposed Changes

The error stems from a faulty assumption in the HTTP API logic: that any state in the hot database must have its block in fork choice. This isn't true because the state's hot database may update much less frequently than the fork choice store, e.g. if reconstructing states (where freezer migration pauses), or if the freezer migration runs slowly. There could also be a race between loading the hot state and checking fork choice, e.g. even if the finalization migration of DB+fork choice were atomic, the update could happen between the 1st and 2nd calls.

To address this I've changed the HTTP API logic to use the finalized block's execution status as a fallback where it is safe to do so. In the case where a block is non-canonical and prior to finalization (permanently orphaned) we default `execution_optimistic` to `true`.

## Additional Info

I've also added a new CLI flag to reduce the frequency of the finalization migration as this is useful for several purposes:

- Spacing out database writes (less frequent, larger batches)
- Keeping a limited chain history with high availability, e.g. the last month in the hot database.

This new flag made it _substantially_ easier to test this change. It was extracted from `tree-states` (where it's called `--db-migration-period`), which is why this PR also carries the `tree-states` label.

   - `BroadcastValidationQuery`, the corresponding HTTP query string type for the above type
 - ~~Define `_checked` variants of both `publish_block` and `publish_blinded_block` that enforce a validation level at a type level~~
 - Add interactive tests to the `bn_http_api_tests` test target covering each validation level (to their own test module, `broadcast_validation_tests`)
   - `beacon/blocks`
       - `broadcast_validation=gossip`
         - Invalid (400)
         - Full Pass (200)

          - Only consensus (400)
          - Pass (200)
 - Add a new trait, `IntoGossipVerifiedBlock`, which allows type-level guarantees to be made as to gossip validity
 - Modify the structure of the `ObservedBlockProducers` cache from a `(slot, validator_index)` mapping to a `((slot, validator_index), block_root)` mapping
 - Modify `ObservedBlockProducers::proposer_has_been_observed` to return a `SeenBlock` rather than a boolean on success
 - Punish gossip peer (low) for submitting equivocating blocks
 - Rename `BlockError::SlashablePublish` to `BlockError::SlashableProposal`

affea585f4 Remove CountUnrealized (#4357)
## Issue Addressed

Closes #4332

## Proposed Changes

Remove the `CountUnrealized` type, defaulting unrealized justification to _on_. This fixes the #4332 issue by ensuring that importing the same block to fork choice always results in the same outcome.

Finalized sync speed may be slightly impacted by this change, but that is deemed an acceptable trade-off until the optimisation from #4118 is implemented.

TODO:

- [x] Also check that the block isn't a duplicate before importing
