For now I suggest we remove this functionality, and at some point we may
consider replacing it with a `remove-disk` action.

Helper functions for the ceph charms. This library has shared functionality that is used in the ceph-mon, ceph-osd and ceph
charms. Anything that needs to be shared across the ceph charms should live here.
