2. **Support VolumeSnapshotClass selection at PVC level**
The user can annotate the PVCs with driver and VolumeSnapshotClass name. The CSI plugin will use the VolumeSnapshotClass specified in the annotation. If the annotation is not present, the CSI plugin will use the default VolumeSnapshotClass for the driver. If the VolumeSnapshotClass provided is of a different driver, the CSI plugin will use the default VolumeSnapshotClass for the driver.
