6ec649a4e2 Optimise head block root API (#4799)
## Issue Addressed

We've had a report of sync committee performance suffering with the beacon processor HTTP API prioritisations.

## Proposed Changes

Increase the priority of `/eth/v1/beacon/blocks/head/root` requests, which are used by the validator client to form sync committee messages, here:

441fc1691b/validator_client/src/sync_committee_service.rs (L181-L188)

Additionally, avoid loading the blinded block in all but the `block_id=block_root` case. I'm not sure why we were doing this previously, I suspect it was just an oversight during the implementation of the `finalized` status on API requests.

## Additional Info

I think this change should have minimal negative impact as:

- The block root endpoint is quick to compute (a few ms max).
- Only the priority of `head` requests is increased. Analytical processes that are making lots of block root requests for past slots are unable to DoS the beacon processor, as their requests will still be processed after attestations.

7605494791 Use only lighthouse types in the mock builder (#4793)
## Proposed Changes

- only use LH types to avoid build issues
- use warp instead of axum for the server to avoid importing the dep

## Additional Info

- wondering if we can move the `execution_layer/test_utils` to its own crate and import it as a dev dependency
- this would be made easier by separating out our engine API types into their own crate so we can use them in the test crate
- or maybe we can look into using reth types for the engine api if they are in their own crate

dcd69dfc62 Move dependencies to workspace (#4650)
## 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.
closes https://github.com/sigp/lighthouse/issues/4651

5a35278aea Add more checks and logging before genesis (#4730)
## Proposed Changes

This PR adds more logging prior to genesis, particularly on networks that start with execution enabled.

There are new checks using `eth_getBlockByHash/Number` to verify that the genesis state's `latest_execution_payload_header` matches the execution node's genesis block.

The first commit also runs the merge-readiness/Capella-readiness checks prior to genesis. This has two effects:

- Give more information on the execution node's status and its readiness for genesis.
- Prevent the `el_offline` status from being set on `/eth/v1/node/syncing`, which previously caused the VC to complain loudly.

I would like to include this for the Holesky reboot. It would have caught the misconfig that doomed the first Holesky.

## Additional Info

- Geth doesn't serve payload bodies prior to genesis, which is why we use the legacy methods. I haven't checked with other ELs yet.
- Currently this is logging errors with _Capella_ genesis states generated by `ethereum-genesis-generator` because the `withdrawals_root` is not set correctly (it is 0x0). This is not a blocker for Holesky, as it starts from Bellatrix (Pari is investigating).

4b6cb3db2c Prevent port re-use in HTTP API tests (#4745)
## Issue Addressed

CI is plagued by `AddrAlreadyInUse` failures, which are caused by race conditions in allocating free ports.

This PR removes all usages of the `unused_port` crate for Lighthouse's HTTP API, in favour of passing `:0` as the listen address. As a result, the listen address isn't known ahead of time and must be read from the listening socket after it binds. This requires tying some self-referential knots, which is a little disruptive, but hopefully doesn't clash too much with Deneb 🤞

There are still a few usages of `unused_tcp4_port` left in cases where we start external processes, like the `watch` Postgres DB, Anvil, Geth, Nethermind, etc. Removing these usages is non-trivial because it's hard to read the port back from an external process after starting it with `--port 0`. We might be able to do something on Linux where we read from `/proc/`, but I'll leave that for future work.

e4ed317b76 Add Experimental QUIC support (#4577)
## Issue Addressed

#4402 

## Proposed Changes

This PR adds QUIC support to Lighthouse. As this is not officially spec'd this will only work between lighthouse <-> lighthouse connections. We attempt a QUIC connection (if the node advertises it) and if it fails we fallback to TCP. 

This should be a backwards compatible modification. We want to test this functionality on live networks to observe any improvements in bandwidth/latency.

NOTE: This also removes the websockets transport as I believe no one is really using it. It should be mentioned in our release however.

74eb267643 Remove double-locking deadlock from HTTP API (#4687)
## Issue Addressed

Fix a deadlock introduced in #4236 which was caught during the v4.4.0 release testing cycle (with thanks to @paulhauner and `gdb`).

## Proposed Changes

Avoid re-locking the fork choice read lock when querying a state by root in the HTTP API. This avoids a deadlock due to the lock already being held.

## Additional Info

The [RwLock docs](https://docs.rs/lock_api/latest/lock_api/struct.RwLock.html#method.read) explicitly advise against re-locking:

> Note that attempts to recursively acquire a read lock on a RwLock when the current thread already holds one may result in a deadlock.

8e95b69a1a Send success code for duplicate blocks on HTTP (#4655)
## Issue Addressed

Closes #4473 (take 3)

## Proposed Changes

- Send a 202 status code by default for duplicate blocks, instead of 400. This conveys to the caller that the block was published, but makes no guarantees about its validity. Block relays can count this as a success or a failure as they wish.
- For users wanting finer-grained control over which status is returned for duplicates, a flag `--http-duplicate-block-status` can be used to adjust the behaviour. A 400 status can be supplied to restore the old (spec-compliant) behaviour, or a 200 status can be used to silence VCs that warn loudly for non-200 codes (e.g. Lighthouse prior to v4.4.0).
- Update the Lighthouse VC to gracefully handle success codes other than 200. The info message isn't the nicest thing to read, but it covers all bases and isn't a nasty `ERRO`/`CRIT` that will wake anyone up.

## Additional Info

I'm planning to raise a PR to `beacon-APIs` to specify that clients may return 202 for duplicate blocks. Really it would be nice to use some 2xx code that _isn't_ the same as the code for "published but invalid". I think unfortunately there aren't any suitable codes, and maybe the best fit is `409 CONFLICT`. Given that we need to fix this promptly for our release, I think using the 202 code temporarily with configuration strikes a nice compromise.
