* Fix issue when VC unable to detect errors properly and act accordingly. Switch all API functions used by VC to RestPlainResponse, this allows us to print errors returned by BN servers. * Fix issue when prepareBeaconCommitteeSubnet() do not perform actions when BN is optimistically synced only. * Fix Defect issue. * Fix submit/publish returning `false` when operation was successful. * Address review comments. * Fix some client calls unable to receive `execution_optimistic` field, mark BN as OptSynced when such request has been made. * Adjust warning levels. --------- Co-authored-by: Jacek Sieka <jacek@status.im>
