Update git submodules

* Update docs/submodules/oom.git from branch 'master'
  to b9c9959e777c35332e007b5e4c1d919c47291013
  - Merge "fix /home/ansible ownership"
  - fix /home/ansible ownership

    in k8s, the nfs mount point
    was assigned to /home/ansible
    that caused the issue where
    /home/ansible becomes to root:root
    so moved to /var/local

    and also updated to the laest version
    that contains the latest fix
