Distinct between unexpected data and unexpected code.
Deprecate Option[T] usage.

Get proper string conversion for strategy.
* Fix SSZ encoded versions of ProduceBlockResponseV2, ProduceBlockResponseV2 can be received and decoded.
Fix done() warnings.
Bump presto.
* Fix compilation error with new presto.
Use TcpNoDelay option for Web3Signer.
* Fix produceBlockV2() should provide SSZ responses too.
* Address block encoding issue.

* Refactor nimbus_signing_node to support Unix signals.
* Fix SN unable to close REST server properly.
* Fix `keys`, `deposit` and `validator_registration` endpoints issues.
Add getValidatorExitSignature() and getDepositMessageSignature() to validator_pool.
* Add /reload endpoint and implementation.
Fix signData to not cancel `timer`.
Fix validator_pool should clear attachedValidators table.
* Diva protocol enhancement implementation.
* log validator that triggers doppelganger
* move activity detection closer to where it's performed, record
aggregation as activity (since it's part of the liveness endpoint)
* vc: check for doppelgangers in epoch 0 also (so that activity in epoch
1 can happen)
* avoid some looping when processing activities
* restore doppelganger check on connectivity loss
https://github.com/status-im/nimbus-eth2/pull/4398 introduced a
regression in functionality where doppelganger detection would not be
rerun during connectivity loss. This PR reintroduces this check and
makes some adjustments to the implementation to simplify the code flow
for both BN and VC.
* track when check was last performed for each validator (to deal with
late-added validators)
* track when we performed a doppel-detectable activity (attesting) so as
to avoid false positives
* remove nodeStart special case (this should be treated the same as
adding a validator dynamically just after startup)
* allow sync committee duties in doppelganger period
* don't trigger doppelganger when registering duties
* fix crash when expected index response is missing
* fix missing slashingSafe propagation
We do a linear scan of all pubkeys for each validator and slot - this
becomes expensive with large validator counts.
* normalise BN/VC validator startup logging
* fix crash when host cannot be resolved while adding remote validator
* silence repeated log spam for unknown validators
* print pubkey/index/activation mapping on startup/validator
identification
* fix REST liveness endpoint responding even when gossip is not enabled
* fix VC exit code on doppelganger hit
* fix activation epoch not being updated correctly on long deposit
queues
* fix activation epoch being set incorrectly when updating validator
* move most implementation logic to `validator_pool`, add tests
* ensure consistent logging between VC and BN
* add docs
* Types and scaffolding for EIP-4844
This commit adds the EIP-4844 spec types, and fills in
scaffolding/boilerplate for the use of these types across the repo.
None of the actual EIP-4844 logic is introduced yet.
This follows the pattern used by @tersec when introducing Capella (#4276).
* use eth2-networks fork
* review feedback: add static check EIP4844_FORK_EPOCH == FAR_FUTURE_EPOCH
* review feedback: remove EIP4844 from /eth/v1/config/spec response
* Cleanup / review feedback
* Fix REST test
