> 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.
