      - 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 PV/PVC for elasticsearch has it was hardcoded to
        hostPath.

        I've also removed hostPath for job logs (aai-traversal logs were not put
        into the desired hostPath)

        And I moved the 3 jobs of aai-graphadmin into 3 files as it's a better
        practice (several object in the same file can lead to unexpected
        behavior).

        Behavior is supposed to be exactly the same as before.
