[LTP] [PATCH v3 07/19] API/cgroup: Add more controllers to tst_cgroup

[Luke Nowakowski-Krijger]

Add the rest of the controllers that are tested in LTP controller tests
so that they can be mounted using the cgroup api.

Control files should be added on an as needed basis.

v2: remove rdma controller as that is not used in any LTP tests.
Remove control files that should be added on an as needed basis.
v3: Add debug controllers
