commit 4a8dea80e8df494ef4c325f12c12418367b4720e
Author: James Peach <jp...@apache.org>

Kill stray tasks when tearing down test cgroups.
If a test case fails, it may leave stray tasks in the cgroup which keeps
us from tearing it down when the test completes. Kill any stray tasks
before destroying the cgroup.

commit 623e467913f1a91a965c0c37397bac583c9706c1
Author: James Peach <jp...@apache.org>

Mount all supported subsystems in the containerizer tests.
Rather than a hard-coded list of subsystems, just mount everything we
find that is supported.
