* Update docs/submodules/multicloud/k8s.git from branch 'master'
  to 3d8e9a41d55cd862e9963e8c561e80f9ec09d484
  - Merge "add cmk in KuD"
  - add cmk in KuD

    - deploy cmk related pods
    - untaint compute nodes if necessary
    - run cmk unit tests: allocate CPUs from exclusive and shared pools
    - deploy a testing nginx pod along with cmk testing pods
    - preset 1/2 CPUs for shared/exlusive pools to fit CI server machines
      users can adjust the parameters to meet their own requirements

    Test Results:
      - many rounds of vagrant/5 VMs(controller01/02/03 and compute01/02)
        based test are all OK
      - 14 rounds tests on my local server (S2600WFQ (36C/72T) )and
        PC(HP Z228 (4C/4T)) with all-in-one bare metal deployment are all OK
      - CI(a 4C/4T machine) results of latest patch set also show that the
        test of bare metal deployment is OK
      - NOTE: both my local test and CI use the same testing method of calling
              aio.sh after applying the latest patch set.
