Simplify Transport*OperationAction names

As a follow up to elastic#11332, this commit simplifies more class names by remove the superfluous Operation:

TransportBroadcastOperationAction -> TransportBroadcastAction
TransportMasterNodeOperationAction -> TransportMasterNodeAction
TransportMasterNodeReadOperationAction -> TransportMasterNodeReadAction
TransportShardSingleOperationAction -> TransportSingleShardAction
