This ensures that charms don't try to upgrade themselves everytime
an update-status hook call occurs; specifically we need to map the
numerical version to the latest OpenStack release that carries
that version for the UCA.

Gnocchi does always major release with OpenStack.

Enable snap installation support for Gnocchi.

The Gnocchi snap provides nginx and uwsgi instead of
Apache2 + mod_wsgi so the config/restart map looks a
little different.

Snap support has been implemented using a subclass of
the GnocchiCharmBase class, which provides common
methods and properties to both deb and snap based
installations.

Snaps are only published for Ocata or later releases
of OpenStack.
