[nisgoel-amazon]

What is the bug?
RetentionLeaseInvalidRetainingSeqNoException is coming when leader cluster is having retention lease and on follower cluster someone try to start replication with same index name.

[2023-04-02T22:50:40,816][ERROR][o.o.r.r.RemoteClusterRepository] [4c49dc0e6b723fdade00f0e3b35fe316] Restore of shard from remote cluster repository failed permanently after all retries due to RetentionLeaseInvalidRetainingSeqNoException[the current retention lease with [replication:613844886458:aid-mktplce:[compteamprimary][1]] is retaining a higher sequence number [13301] than the new retaining sequence number [13296] from [replication:613844886458:aid-mktplce]]

How can one reproduce the bug?
Steps to reproduce the behavior:

1. Create connection between follower and leader domain
2. Start the replication on index1
3. Delete the connection between cluster, replication went to autopause and lease on leader will not be deleted as there is no connection.
4. Create the connection again with same alias name
5. Then start the replication of same index after deleting index from follower.

What is the expected behavior?
Replication should start successfully without giving RetentionLeaseInvalidRetainingSeqNoException
