-------------------------------

Sorry this is low priority for me right now so I am unassigning.

> cgroups_tests not correctly tearing down testing hierarchies

> We currently do the following in 
> [CgroupsTest::TearDownTestCase()|https://github.com/apache/mesos/blob/5e850a362edbf494921fedff4037cf4b53088c10/src/tests/containerizer/cgroups_tests.cpp#L83]
> {code:title=}
> static void TearDownTestCase()
> {
>   AWAIT_READY(cgroups::cleanup(TEST_CGROUPS_HIERARCHY));
> }
> {code}
> One of its derived test {{CgroupsNoHierarchyTest}} treats 
> {{TEST_CGROUPS_HIERARCHY}} as a hierarchy so it's able to clean it up as a 
> hierarchy.
> However another derived test {{CgroupsAnyHierarchyTest}} would create new 
> hierarchies (if none is available) using {{TEST_CGROUPS_HIERARCHY}} as a 
> parent directory (i.e., base hierarchy) and not as a hierarchy, so when it's 
> time to clean up, it fails:
> {noformat:title=}
> [       OK ] CgroupsAnyHierarchyTest.ROOT_CGROUPS_Subsystems (1 ms)
> ../../src/tests/containerizer/cgroups_tests.cpp:88: Failure
> (cgroups::cleanup(TEST_CGROUPS_HIERARCHY)).failure(): Operation not permitted
> {noformat}
