cephfs: Add clusterName as metadata on snapshots

Browse Source 
Example:
sh-4.4$ ceph fs subvolume snapshot metadata ls myfs csi-vol-ba248f9e-0e75-11ed-b774-8e97192ff5ec \
			csi-snap-ce24e3bb-0e75-11ed-b774-8e97192ff5ec --group_name csi
{
    "csi.ceph.com/cluster/name": "\"K8s-cluster-1\"",
    "csi.storage.k8s.io/volumesnapshot/name": "cephfs-pvc-snapshot",
    "csi.storage.k8s.io/volumesnapshot/namespace": "rook-ceph",
    "csi.storage.k8s.io/volumesnapshotcontent/name": "snapcontent-2e89e1b2-e6e9-48fe-b365-edb493d7022e"
