Update git submodules

* Update docs/submodules/oom.git from branch 'master'
  to 8f9e119c3c3a98a0757b14b9b9da6404d6b81d28
  - Merge "MetalLB install script for bare metal cluster"
  - MetalLB install script for bare metal cluster

    If Ingress controller is exposed via NodePort
    it listens on non standard port, so it can be
    quite problematic.  Exposing via LoadBalancer
    doesn't work properly on bare metal Kubernetes
    cluster, so external LB solution is needed.
