> 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.
