* Update docs/submodules/oom.git from branch 'master'
  to af7fd0ed77933189c1f2263e078c38e4c65f4c86
  - Merge "Fix readiness-check ready.py script for stateful set"
  - Fix readiness-check ready.py script for stateful set

    Only check the status field readyReplicas instead of
    currentReplicas and updatedReplicas. The value of currentReplicas
    relates to the number of pods created with the first revision of
    the stateful set. If a change is made to the stateful set and pods are restarted
    then currentReplicas is no longer returned in the status.
    Check JIRA for more information.
