For migration of services to execution under Python 3 add support
for a Charm class to declare a set of packages to purge on upgrade.
This allows the target release Charm class to remove Python 2
modules installed as part of prior charm versions.
After the purge call, autoremove will also be called to purge any
other packages that where indirectly installed.
Add new python_version attribute for charm classes, supporting
conditional install of python{3}-memcache for token caching.
