This reverts commit a3f919205a.
* `selectPeers`: Avoid map with key but empty value.
* Fix Potuz's comment.
* Add DataColumnStorage and SubscribeAllDataSubnets flag.
* getBlobsV2: retry if reconstruction isnt successful
* test: engine client and sync package, metrics
* lint: fmt and log capitalisation
* lint: return error when it is not nil
* config: make retry interval configurable
* sidecar: recover function and different context for retrying
* lint: remove unused field
* beacon: default retry interval
* reconstruct: load once, correctly deliver the result to all waiting goroutines
* reconstruct: simplify multi goroutine case and avoid race condition
* engine: remove isDataAlreadyAvailable function
* sync: no goroutine, getblobsv2 in absence of block as well, wrap error
* exec: hardcode retry interval
* da: non blocking checks
* sync: remove unwanted checks
* execution: fix test
* execution: retry atomicity test
* da: updated IsDataAvailable
* sync: remove unwanted tests
* bazel: bazel run //:gazelle -- fix
* blockchain: fix CustodyGroupCount return
* lint: formatting
* lint: lint and use unused metrics
* execution: retry logic inside ReconstructDataColumnSidecars itself
* lint: format
* execution: ensure the retry actually happens when it needs to
* execution: ensure single responsibility, execution should not do DA check
* sync: don't call ReconstructDataColumnSidecars if not required
* blockchain: move IsDataAvailable interface to blockchain package
* execution: make reconstructSingleflight part of the service struct
* blockchain: cleaner DA check
* lint: formatting and remove confusing comment
* sync: fix lint, test and add extra test for when data is actually not available
* sync: new appropriate mock service
* execution: edge case - delete activeRetries on success
* execution: use service context instead of function's for retry
* blockchain: get variable samplesPerSlot only when required
* remove redundant function and fix name
* fix test
* fix more tests
* put samplesPerSlot at appropriate place
* tidy up IsDataAvailable
* correct bad merge
* fix bad merge
* remove redundant flag option
* refactor to deduplicate sidecar construction code
* - Add godocs
- Rename some functions to be closer to the spec
- Add err in return of commitments
* Replace mutating public method (but only internally used) `Populate` but private not mutating method `extract`.
* Implement a unique `processDataColumnSidecarsFromExecution` instead 2 separate functions from block and from sidecar.
* `ReceiveBlock`: Wrap errors.
* Remove useless tests.
* `ConstructionPopulator`: Add tests.
* Fix tests
* Move functions to be consistent with blobs.
* `fetchCellsAndProofsFromExecution`: Avoid useless flattening.
* `processDataColumnSidecarsFromExecution`: Stop using DB cache.
