Oliver Walsh 016cef3ea7 Add polkit rule to allow kolla nova user access to libvirtd socket on docker host
The polkit rules are currently evaluated in the context of the docker host.
As a result the check fails for the kolla nova compute user, as the uids are not
consistent with the host uids (in fact we probably can't assume a nova user exists
on the docker host).

As a short-term workaround a 'docker_nova' user group is created on the docker host
and the polkit rule is updated to grant this user access to the libvirtd socket.

Longer term solution probably requires running polkitd in a container too.
