[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.
