Description
Currently the Manager interface supports only adding a process by calling Apply(pid int), but there's no support for adding a thread on thread mode.
Perhaps the current method can be utilized to either add a process or a thread, depending on the cgroup's mode.

Research direction
Start with the Manager interface in libcontainer/cgroups/cgroups.go, especially Apply(pid int), and inspect how cgroup thread mode currently handles process IDs. Determine how the interface should accept a thread ID without breaking process-mode behavior; done means thread IDs can be added to a thread-mode cgroup through the supported Manager API.
