This commit lifts the control of when retention leases are expired to index shard. In this case, we move expiration to an explicit action rather than a side-effect of calling `ReplicationTracker#getRetentionLeases`. This explicit action is invoked on a timer. If any retention leases expire, then we hard sync the retention leases to the replicas. Otherwise, we proceed with a background sync.
