org.elasticsearch.index.seqno.RetentionLeaseSyncAction
public class RetentionLeaseSyncAction extends TransportWriteAction<RetentionLeaseSyncAction.Request,RetentionLeaseSyncAction.Request,RetentionLeaseSyncAction.Response>
Write action responsible for syncing retention leases to replicas. This action is deliberately a write action so that if a replica misses
a retention lease sync then that shard will be marked as stale.
