Remove the hardcoded `backingSnapshot = "false"` override in the NFS controller, enabling NFS volumes to use CephFS snapshot-backed (shallow) read-only volumes. This avoids expensive data cloning when read-only access to snapshot contents is needed. Changes: - Expose `backingSnapshotRoot` in CephFS volume context so the NFS controller can construct the correct export path pointing to the snapshot data directory. - Remove the `backingSnapshot` blocker in NFS CreateVolume and adjust the NFS export path to include the backing snapshot root for snapshot-backed volumes. - Add three NFS e2e tests: snapshot-backed volume, backing snapshot as false, and RWX clone from ROX PVC.
