Update git submodules

* Update docs/submodules/oom.git from branch 'master'
  to 7f68e58cda64be4cf24091840a86b9e8ee6a60b6
  - Merge "Fix issue with etcd pod startup"
  - Fix issue with etcd pod startup

    Etcd pod fails to start with file not found error.
    The error is being caused because the pod is stuck
    in an infinite loop as the readiness probe is not true.
    Since, we are anyway checking the pod status, we removed
    the readiness probe as it is not needed.
    Bumped up version of etcd to 3.2.24
    This fixes a known issue:
