Update git submodules

Update git submodules

* Update docs/submodules/oom.git from branch 'master'
  to d7c871ee5e465c11f36974cfb668844882d139d2
  - Merge "[PNDA] Use global storage templates for PVC"
  - [PNDA] 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

    I've also created a PVC for the job instead of doing a PVC template
    inside the job.
