Canonical are packaging gnocchi-api package with apache
and python3 by default. We cannot test it in CI since
we cannot run py2 and py3 on the same node with apache wsgi.
Canonical helped us by packaging python2 support back into
python-gnocchi package so we change our wsgi usage to use
this package and set the new wsgi script path.
We still want users to be able to install only gnocchi-api
since they might not run apache wsgi even though its installed by
default.
Adds installation of rados and redis packages for python3
when needed, this is because all gnocchi components will
still be running in py3, also CLI such as gnocchi-upgrade
but the gnocchi-api is in wsgi using py2. Because of that
we still need to install the py2 packages.
Enables acceptance testing for Debian based operating systems.
