[Bug 1315521] Re: wrong cgroup on login to container

[Serge Hallyn]

** Description changed:

  When starting a privileged container with cgmanager, cgroups look like:
  
  3:cpuset:/lxc/u5
  2:name=systemd:/user/1000.user/c2.session
  
  where all controllers other than name=systemd are correct.  lxc needs
  to set the new cgroup for name=systemd, and cgmanager needs to fix a
  bug where name=systemd was not being handled right.
+ 
+ ========================================================
+ Impact: containers are not fully placed into their cgroup
+ Test case:
+ 	sudo lxc-create -t download -n u1 -- -d ubuntu -r trusty -a amdte
+ 	sudo lxc-start -n u1 -d
+ 	sudo lxc-attach -n u1 -- grep systemd /proc/self/cgroup
+ 	Verify that the cgroup is /lxc/u1
+ Regression potential: This implements a new method rather than
+ modifying existing methods.  Existing functionality should not
+ be changed.
+ ========================================================
