Update charm to execute hooks and actions under Python 3; this includes dealing with upgrades (by switching the upgrade-charm hook to be a bash script which installs the required charm runtime dependencies). This commit also drops code from ceph.py which was used across other ceph charms in the past; only the functions required for this charm have been retained.
