F #6564: Fix ceph monitor quotas (#3042)

There are two monitor scripts for Ceph datastores:

- src/tm_mad/ceph/monitor (ds SYSTEM)
- src/datastore_mad/remotes/ceph/monitor (ds IMAGE)

The two have the same logic but the first one had diverted from the
second one slightly, making it unable to handle quotas.  This commit
symlinks them to avoid this happening again in the future, and fixes the
relative paths to ensure they work both from the DS and TM drivers
paths.
