Update git submodules

* Update docs/submodules/oom.git from branch 'master'
  to 9d4cdf7ef706b85ec1d86b4945812d61cbdb3f15
  - Merge "[ESR] Force esr-server to run as non-root"
  - [ESR] Force esr-server to run as non-root

    Use securityContext to run esr-server as a non-root user.
    Unfortunately esr-server docker is built in a way that doesn't allow use
    to just change the user and continue using it. We need to make sure
    that conf dir is writable for this user because this docker modifies
    its configuration files from docker_entrypoint.sh
