Use normal socket file permissions instead of polkit
The default (on RHEL/CentOS) is to use polkit but this is only useful for GUI support or for fine grained API access control. As we don't require either we can achieve identical control using plain old unix filesystem permissions. I've merged Sven's changes from https://review.openstack.org/484979 and https://review.openstack.org/487150. As we need to be careful with the libvirtd option quoting I think it's best to do this in puppet-tripleo instead of t-h-t yaml. The option to override the settings from t-h-t remains.
