Update git submodules

* Update docs/submodules/oom.git from branch 'master'
  to 5e6170cfb2f027e56e6935ef2059900976271a3d
  - Merge "Introduce postinstall configuration onboarding for Kibana pod (part 1 of 2)."
  - Introduce postinstall configuration onboarding for Kibana pod (part 1 of 2).

    * The configuration is stored in "log/charts/log-kibana/resources/config/kibana-onboarding.json".
    * Running Kibana configuration can be dumped using Elasticdump tool.
    * At the moment the "kibana-onboarding.json" file is empty, so the commit should not break anything.
    * In an upcoming commit we will add onboarding procedure described in https://wiki.onap.org/pages/viewpage.action?pageId=24642176
