Update git submodules

* Update docs/submodules/oom.git from branch 'master'
  to 61b1c7bef72bf31e0c5b4c3241121e43082a1a01
  - Merge "[Portal] Move (unused) readinessImage to global"
  - [Portal] Move (unused) readinessImage to global

    All helm charts in ONAP are setting readinessImage to global part (it
    can then be easy to bump version for everybody at once).

    Portal Job is not using it and use a local version.
    Move to use global one for consistency
