Update git submodules

* Update docs/submodules/oom.git from branch 'master'
  to 03b1009c7b791ea3252237f79367ff0501460f16
  - Remove additional _helpers files

    Helm by default creates some useful templates in _helpers.tpl
    file. This is fine for stand alone charts but when they become
    part of ONAP those helpers are no longer needed as our common
    components already provides all required functions
