Add support for persistent volume claims in kube files
In k8s a persistent volume claim (PVC) allow pods to define a volume by referencing the name of a PVC. The PVC basically contains criterias that k8s then use to select which storage source it will use for the volume. Podman only provide one abtracted storage, the named volumes, and create them if they don't exists yet. So this patch simply use a volume with the name of the PVC.
