/eth/v1/beacon/pool/sync_committees

Submit sync committee signatures to node.

Sends objects with the sync committee signature to the node.

Signatures from the sync committee are necessary for Altair networks but are absent from phase 0.

A node MUST broadcast a sync committee signature on all relevant subnets if it has been validated successfully.

The node MUST provide a 400 error including information about which sync committee signatures have failed and why if one or more of them fail validation.
