nspawn: suffix the nspawn cgroups with ".nspawn"
As discussed with Dan Berrange it's a good idea to suffix all objects in the cgroup tree with ".something", so that when the system is partitioned using a resource management tool we can drop objects of different types into the same partition directory without generate namespace conflicts. We'l add this to the Pax Control Group document as soon as write access to the fdo wiki is restored.
