#7756 introduces a logging issue, where the relevant log:
da5b231720/beacon_node/network/src/network_beacon_processor/rpc_methods.rs (L380-L385)
obtains the `block_root` from `slots_by_block_root.keys()`. If the `block_root` is empty (block not found in the data availability checker), then the log will not show any block root:
`DEBUG BlobsByRoot outgoing response processed peer_id: 16Uiu2HAmCBxs1ZFfsbAfhSA98rUUL8Q1egLPb6WpGdKZxX6HqQYX, block_root: [], returned: 4`

We were publishing columns all columns that we didn't already have in the da cache when reconstructing. This is unnecessary outbound bandwidth for the node that is supposed to sample fewer columns.

This PR adds backfill functionality to nodes switching to become a supernode or semi-supernode. Please note that we currently only support a CGC increase, i.e. if the node's already custodying 67 columns, switching to semi-supernode (64) will have no effect.

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

#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.

This recent PR below changes the max reconstruction delay to be a function of slot time. However it uses `seconds_from_slot_start` when comparing (and dropping `nano`), so it might delay reconstruction on networks where the slot time isn’t a multiple of 4, e.g. on gnosis this only happens at 2s instead of 1.25s.:

N/A
1. In the batch retry logic, we were failing to set the batch state to `AwaitingDownload` before attempting a retry. This PR sets it to `AwaitingDownload` before the retry and sets it back to `Downloading` if the retry suceeded in sending out a request
2. Remove all peer scoring logic from retrying and rely on just de priorotizing the failed peer. I finally concede the point to @dapplion 😄
3. Changes `block_components_by_range_request` to accept `block_peers` and `column_peers`. This is to ensure that we use the full synced peerset for requesting columns in order to avoid splitting the column peers among multiple head chains. During forward sync, we want the block peers to be the peers from the syncing chain and column peers to be all synced peers from the peerdb.
Also, fixes a typo and calls `attempt_send_awaiting_download_batches` from more places

This PR reverts #8179.
It turns out that the fix was invalid because an unknown root is always not a finalized descendant:
522bd9e9c6/consensus/proto_array/src/proto_array.rs (L976-L979)
so for any data columns with unknown parents, it will always penalise the gossip peer and disconnect it pretty quickly. On a small network, the node may lose all of its peers.
The impact is pretty obvious when the peer count is small and sync speed is slow, and is therefore easily reproducible by running a fresh supernode on devnet-3.
This isn't as obvious on a live testnet like holesky / sepolia, we haven't noticed this, probably due to its high peer count and sync speed - the nodes might be able to reach head quickly before losing too many peers.
The previous behaviour isn't ideal but safe: triggering unknown parent lookup and penalise the bad peer if it happens to be malicious or faulty. So for now it's safer to revert the change and plan for a proper fix after the v8 release.

```
So if any of the block components arrives late, then we reconstruct all 128 columns and try to add it to da cache and have more columns than needed for availability in the cache.
There are 2 ways I can think of fixing this:
1. pass only the required columns to the da cache after reconstruction here 60df5f4ab6/beacon_node/beacon_chain/src/data_availability_checker.rs (L647-L648)
2. Ensure that we add only columns that we need to sample in the da cache. I think this is safer since we can add columns to the cache from multiple code paths and this fixes it at the source.
~~This PR implements (2).~~ Thought more about it, I think (1) is cleaner since we filter gossip and rpc columns also before calling `put_kzg_verified_data_columns`/

Co-Authored-By: Michael Sproul <michael@sigmaprime.io>
This issue was identified during the fusaka audit competition.
The [`verify_parent_block_and_finalized_descendant`](62d9302e0f/beacon_node/beacon_chain/src/data_column_verification.rs (L606-L627)) in data column gossip verification currently load the parent first before checking if the column descends from the finalized root.
However, the `fork_choice.get_block(&block_parent_root)` function also make the same check internally:
8a4f6cf0d5/consensus/fork_choice/src/fork_choice.rs (L1242-L1249)
Therefore, if the column does not descend from the finalized root, we return an `UnknownParent` error, before hitting the `is_finalized_checkpoint_or_descendant` check just below.
Which means we `IGNORE` the gossip message instead `REJECT`, and the gossip peer is not _immediately_ penalised. This deviates from the spec.
However, worth noting that lighthouse will currently attempt to request the parent from this peer, and if the peer is not able to serve the parent, it gets penalised with a `LowToleranceError`, and will get banned after ~5 occurences.
ffa7b2b2b9/beacon_node/network/src/sync/network_context.rs (L1530-L1532)
This PR will penalise the bad peer immediately instead of performing block lookups before penalising it.

Post fulu, we should be calling the v2 api on the relays that doesn't return the blobs/data columns.
However, we decided to start hitting the v2 api as soon as fulu is scheduled to avoid unexpected surprises at the fork.
In the ACDT call, it seems like most clients are calling v2 only after the fulu fork.
This PR aims to be the best of both worlds where we fallback to hitting v1 api if v2 fails. This way, we know beforehand if relays don't support it and can potentially alert them.

We're also seeing similar `WARN` logs for blobs on our live nodes.
It's normal to get parent unknown in lookups and it's handled here
a134d43446/beacon_node/network/src/sync/block_lookups/mod.rs (L611-L619)
These shouldn't be a `WARN`, and we also log the same error in block lookups at `DEBUG` level here:
a134d43446/beacon_node/network/src/sync/block_lookups/mod.rs (L643-L648)
So i've removed these extra WARN logs.
I've also lower the level of an `ERROR` log when unable to serve data column root requests - it's unexpected, but is unlikely to impact the nodes performance, so I think we can downgrade this.

In the methods that compute the proposer shuffling decision root, ensure we don't use lookahead for the Fulu fork epoch itself. This is accomplished by checking if Fulu is enabled at `epoch - 1`, i.e. if `epoch > fulu_fork_epoch`.
I haven't updated the methods that _compute_ shufflings to use these new corrected bounds (e.g. `BeaconState::compute_proposer_indices`), although we could make this change in future. The `get_beacon_proposer_indices` method already gracefully handles the Fulu boundary case by using the `proposer_lookahead` field (if initialised).

In #8101 , when we modified the logic to get the proposer index post fulu, we seem to have missed advancing the state at the fork boundaries to get the right `Fork` for signature verification.
This led to lighthouse failing all gossip verification right after transitioning to fulu that was observed on the holesky shadow fork
