Update git submodules

* Update docs/submodules/oom.git from branch 'master'
  to b76e563c2091b311450ada9c9e702bd44f7de734
  - Merge "[CDS] Use global storage templates for PVC"
  - [CDS] Use global storage templates for PVC

    OOM has now templates in order to create the needed PVC, using:

    * a PV with a specific class when using a common nfs mount path between
    nodes (sames as today use) --> is the default behavior today
    * or a storage class if we want to use dynamic PV.
      On this case, we use (in order of priority):
      - persistence.storageClassOverride if set on the chart
      - global.persistence.storageClass if set globally
      - persistence.storageClass if set on the chart
