  - Merge "Move Modeling Storage to RWO"
  - Move Modeling Storage to RWO

    Today when deploying Policy with OOM, the PersistentVolumeClaim needs the
    "ReadWriteMany" (or "RWX") capability.

    According to Kubernetes Documentation (https://kubernetes.io/docs/concepts/storage/persistent-volumes/#access-modes),
    ReadWriteMany stands for "the volume can be mounted as read-write by many nodes".

    That means that a particular PVC needs to be read and written from many pods.
    That also means that your code takes that into account and do the work to avoid
    write at the same place at the same time.

    An issue on RWX mode is that most "official" storage driver from Kubernetes doesn't
    support it (13 over the 19 drivers doesn't support it, espacially OpenStack, Amazon
    and Google storage classes).

    Modeling PVC for is used only for one POD.
    Thus we don't need RWX.
