List protected consistency groups in VRG and DRPC

[ELENAGER]

When protecting standalone PVCs, we are displaying flat list of protected PVCs in both VRG and DRPC. When working with consistency groups, we want to display the list of protected consistency groups each one with it's protected PVCs for better understanding the hierarchy
Sample of DRPC showing protected consistency group with list of PVCs:

  resourceMeta:
    generation: 1
    kind: VolumeReplicationGroup
    name: deployment-rbd-drpc
    namespace: deployment-rbd
    protectedcgs:
    - name: rook-ceph-dr1-1deployment-rbd-drpc
      protectedpvcs:
      - extra-pvc
      - busybox-pvc
    resourceVersion: "350102"

Sample of VRG, showing protected consistency group with list of PVCs:
