Review comment:
Can we add a description, if this is not set the we will fall back to
ozone.om.ratis.storage dir/ozone.om.metadirs.
And also add a description similar to other db dirs, fall back is not
recommended for production.

> If a follower OM is lagging way behind the leader OM or in case of a restart
> or bootstrapping, a follower OM might need RocksDB checkpoint from the leader
> to catch up with it. This is because the leader might have purged its logs
> after taking a snapshot.
> This Jira aims to add support to download a RocksDB checkpoint from leader
> OM to follower OM through a HTTP servlet. We reuse the DBCheckpoint servlet
> used by Recon server.
