Update git submodules

* Update docs/submodules/oom.git from branch 'master'
  to 5d620cbbd75517d6d60600debe0f5f5281538580
  - Merge "Add ONAP core deployment type override"
  - Add ONAP core deployment type override

    This patch makes heavy use of Orange accomplishments [1][2][3]. This
    deployment override will probably succeed "minimal-onap.yaml" used in
    e.g. "integration/bootstrap/vagrant-minimal-onap" setup.

    Cassandra replicaCount is increased to 3 to allow reaching quorum.
