Open Stack

Hello,

> I'd like to phase out openstack/openstack-ansible-tests and
> openstack/openstack-ansible later.

Now that we had the time to bump the roles in openstack-ansible, and
adapt the tests, we can now EOL the rest of newton, i.e.:
openstack/openstack-ansible and openstack/openstack-ansible-tests.

Thanks for the help again Tony!
