The existing "manila-grenade" job relies on
devstack-gate, a deprecated project. The Grenade
project now has a native zuulv3 style job that
we can inherit and run manila's upgrade tests.
Manila's grenade tests are only going to run
API tests, and hence this grenade job doesn't
have to enable nova, cinder, glance, neutron
and swift. However, bug #1887835 prevents
us from disabling nova at the moment,
and nova requires glance, placement and neutron
to be deployed, so we'll be enabling these
services too until that bug is addressed.
