python-ceph does not exist under Py3; any dependency on underlying
Python modules is expressed as package dependencies from ceph-*
packages.
python-pyudev is used by ceph.utils and needs to be installed
prior to using pyudev (which is typically done using a bash based
install hook - see ceph-osd for examples).

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.
