    Description

      Since linux kernel 4.6, CGROUP namespace is added. we need to support the handle for the cgroup namespace of the process.

[22:41:26] :	 [Step 10/10] ../../src/tests/containerizer/ns_tests.cpp:75: Failure
[22:41:26] :	 [Step 10/10] nstype: Unknown namespace 'cgroup'
[22:41:26] :	 [Step 10/10] [  FAILED  ] NsTest.ROOT_setns (1 ms)

      [22:41:26] :	 [Step 10/10] [ RUN      ] NsTest.ROOT_getns
