[NO ISSUE][REPL] Ignore LSNs of Partially Replicated Indexes

- user model changes: no

- storage format changes: no

- interface changes: yes

Details:

- When determining low watermark, ignore LSN of replicated

 indexes with no checkpoints.

- Guard logs in case of unexpected min LSN read failures.

- Ensure only one replica is synchronized at a time to prevent

 possible merge operations from deleting files being synchronized

 to another replica concurrently.

- Ensure index metadata files are replicated first to allow

 replicas to find any existing files in case of re-synchronization.

- Ensure replication channel is closed on replication failures.
