[NO ISSUE][REPL] Suspend Dataset Checkpointing on Replica Sync

- user model changes: no
- storage format changes: no
- interface changes: yes

Details:
- Before synchronizing replicas, stop datasets checkpointing to
  prevent new files from being generated due to async IO operations
  triggered by checkpointing.
- Instead of sync'ing current files to replicas then scheduling a flush
  and sync'ing any newly generated files, just flush datasets before
  the initial sync then sync all the files in one go.
