* Skip EL part of graffiti when EL info not available (previously was NA0000)

* Change EL tracker to push either UNKNOWN (when failed) or valuable version

* Electra spec config and builder

There were fields missing for EIP-7251, and also some of the attestation fields. I added the entire diff from consensus-specs while I was going, it seemed easiest...

Added a development flag to allow us to set state regeneration timeout, with a 120 second timeout by default, and a tiny bit of sanity around the flag not being less than 1.

Replace DataColumnSidecarGossipManager with attestation like version

Gossip (part 1)

* Update GossipForkManager and Eth2P2PNetwork
* Add CUSTODY_REQUIREMENT constant
* Create DataColumnSidecarSubnetBackboneSubscriber

More codestyle fixes

…ensys#17)

* Add a number of interface sketches
* Add draft implementations of Custody and CustodySync
* Add necessary spec config constants and functions

* Enable non-canonical sidecars cleanup
* database part2

…ys#21)

* DataColumnReqResp to abstract over network Req/Resp implementation
* DataColumnPeerSearcher to abstract over ConnectionManager + PeerSelectionStrategy
* DataColumnManager which
        notifies on peer connect/disconnect
        can ban peers returning invalid req/resp responses (this could probably fit into existing peers scoring classes)
* DataAvailabilitySampler: minimalistic for now
* Add simple implementations ofDataColumnSidecarRetriever and DataAvailabilitySampler interfaces

* database integration tests
* found a bug with missed commit on pruning, fixed
* minor old interface clarification input name

* removed all Electra features
* renamed from Electra to EIP7594, compatible with spec config
* configs updated to be close to those in spec
* fixed bug with kzg_commitment_inclusion_proof size
* fixed all tests
* modified acceptance test BlockProposalAcceptanceTest to ensure we could run up to EIP7594 fork

…nsys#27)

* added structure checks in kzg verification from the spec
* added proof verification
* fixed kzg_commitment_proof -> kzg_commitments_proof
* logging fixes
* small changes to naming to distinguish with blobs

* Fix el methods for EIP7594

* constructDataColumnSidecars miscHelpers method

…ys#31)

* Adjust DataColumnSidecar creation
* Fix the test compilation

…onsensys#34)

* Disable BlobSidecars availability check in the post Deneb milestones
* More accurate logging

…d sidecars (Consensys#35)

* Integrate DataColumnSidecarCustody for storing gossip inbound/outbound sidecars
* Add suitable sidecars only in DataColumnSidecarCustodyImpl
* Change initialization sequence
* Rename to BlockRootResolver
* Remove stinky comment :)
* Skip initing DasCustody if milestone is not supported

* eference tests 1.5.0.alpha.1 with EIP-7594 coverage activated
* computeCustodyColumnIndexes implemented
* verifyCellProofBatch implemented, it fails badly on some tests, so it's disabled. jc-kzg update should help I think

* Bump reference tests to 1.5.0.alpha.2 + jc-kzg usage update
* fix old import

* Add DiscoveryPeer.getNodeId()
* Use the correct NodeId (from Discovery) instead of wrong Libp2p PeerId when calculating DAS subnets
* Add Eth2Peer.getDiscoveryNodeId() method.

* Refactor:
  *  Make DasPeerCustodyCountSupplier a separate thing
  *  Move DataColumnSidecarRetriever interface to subpackage
* Add DataColumnPeerManagerImpl
* Add BatchDataColumnReqResp and implement it in DataColumnPeerManagerImpl
* Make DataColumnReqResp implementation on top of BatchDataColumnReqResp

* Add draft init code to create DasCustodySync in BeaconChainController
* Make the primitive triggering of SimpleSidecarRetriever: every 1 sec
* Fix GossipForkManager to subscribe currentDataColumnSidecarSubnets on startSubscriptions
* Use the right NodeId in the DataColumnPeerManagerImpl
* BeaconChainController.initDasCustody():
  * subscribe missing elements to slot channel events.
  * Add DasCustodySync start initiator

* Fix NodeRecordConverter.convertPublicKeyToNodeId() (would need more api from discovery to make it more or less nice)
* Align computeDataColumnSidecarBackboneSubnets with current spec
* Make DataColumnBlockRootResolver resolve only blocks with non-empty blob list: blocks without blobs have no columns so we are just ignoring them in the DAS subsystem
* Relax DataColumnSidecarsByRoot RPC slot range requirement for now: will return them back when adopt byRange method variant
* Fix bug in SimpleSidecarRetriever
* Fix something in DasCustodySync
* Fix updating DB firstIncompleteSlot

* spotless
* fix compiler warns
* make tests compile

* Implement GossipTopicDasPeerCustodyTracker
* Refactor DataColumnBlockRootResolver to move more logic from BeaconChainController to DataColumnSidecarCustodyImpl
* Fix the case when extra_column_subnets too large

* NUMBER_OF_COLUMNS is now in config, better to read it
* removed hardcode from fieldElementsPerCell as there is no more division by it

* Reduce MAX_REQUEST_DATA_COLUMN_SIDECARS const to 512
* Fix propagation of call exception to returned future
* Fix/refactor SimpleSidecarRetriever to respect maxRequestCount and the number of currently running requests per peer
* Fix compile error from prev PR

* FirstIncompleteSlot: 'complete' slot should be finalized
* Add logging of inbound DAS RPC requests
* Add more logging details to DataColumnSidecarDBImpl
* Add '[nyota]' prefix to all DAS related logs

* Switch to 'develop' libp2p version
* Add logs on peer connect/disconnect
* Log: fix nodeId output

* Better logging for disconnection reasons 
* request limit increase

* SimpleSidecarRetriever: Add more synchronized
* SimpleSidecarRetriever: add logging stats on the number of custody peers for columns
* P2PConfig.getDasExtraCustodySubnetCount: capped in place with Spec
* GossipTopicDasPeerCustodyTracker: track subscriptions periodically since right after cionnection it may fail as a remote peer didn't yest subscribed
* Cleanup totl/extraCustodySubnetCount mess

…e others do (Consensys#55)

…ys#57)

* Implement long polling req/resp getDataColumnByRoot() method
* Add DataColumnIdentifier.createFromSidecar() factory method
