This argument in csi-provisioner and csi-snapshotter sidecar allows us
to receive additional metadata in the CreateVolume and CreateSnapshot()
request.
For ex:
as part of CreateVolume request:
csi.storage.k8s.io/pvc/name
csi.storage.k8s.io/pvc/namespace
csi.storage.k8s.io/pv/name
and
as part of CreateSnapshot request:
csi.storage.k8s.io/volumesnapshot/name
csi.storage.k8s.io/volumesnapshot/namespace
csi.storage.k8s.io/volumesnapshotcontent/name
This is useful information which can be used depend on the use case we have
at our csi driver level. The features like adding metadata to CephFS subvolume,
RBD image or snapshot can consume this based on the need.
