[SDNC] 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 used "range" for PV creation of the statefulset

I've created one file per PV (one for mdsal, one for certs).

sdnc-prom was using hostpath directly on deployment, move to a PV/PVC.
