switch: disable ceph-disk units

During the transition from jewel non-container to container old ceph
units are disabled. ceph-disk can still remain in some cases and will
appear as 'loaded failed', this is not a problem although operators
might not like to see these units failing. That's why we remove them if
we find them.
