Update git submodules

* Update docs/submodules/oom.git from branch 'master'
  to 284aa85f5b5b3ad1b13f07d6fee3ed163a22eb13
  - Merge "[Modeling] Use common secret template for mariadb root password"
  - [Modeling] Use common secret template for mariadb root password

    Remove hardcoded root password from the modeling chart.
    Because of huge number of issues in modeling docker image
    (see onap-discuss for details) I don't want to touch it.
    That's why I just made an awful hack to concatenate DB
    username and password before the entrypoint script.

    Please keep in mind that this eliminates only hardcoded
    root password but there is plenty of other credentials that
    are boiled into container image (DB, SDC, VCF-REDIS(!) etc).
