[BUG] Index replication task exits after OS restart

[saikaranam-amazon]

Describe the bug
Index replication task exits after OS restart

To Reproduce
Steps to reproduce the behavior:

• Create cluster without dedicated master nodes at the follower side
• Start replication on any index
• Bounce ES env/ Kill ES process on all the nodes
• Verify that the replication is still going on and operation gets synced but the index replication task will be missing

Logs:

Index replication should be running
