> When Ratis server is starting it looks for the latest snapshot to load it. Even though OM does not save snapshots via Ratis, we need to load the saved snaphsot index into Ratis so that the LogAppender knows to not look for logs before the snapshot index. Otherwise, Ratis will replay the logs from beginning every time it starts up.
