Drop service check for ``glance-registry``. The service is
removed as of Stein, and it really is not this charm functional
tests job of checking this anyway. Any such detail should
be deferred to the ``charm-glance`` functional tests.
Update templates/usr.bin.nova-compute as nova-compute requires
read access to /etc/mime.types.
