Creation of VolumeGroupSnapshot fails with error: 
```'failed to create group snapshot content with error snapshot controller failed to update openshift-storage/group-snapshot on API server: Volume CSI driver (ebs.csi.aws.com) mismatch with VolumeGroupSnapshotClass (openshift-storage.rbd.csi.ceph.com) openshift-storage/group-snapshot: pvc-3f4073c2-d28c-45b1-85f5-8cd8eca3d3fa'```

This is because we use matchexpression as label selector while snapshotter-controller only supports matchLabels selector.

```
spec:
  source:
    selector:
      matchExpressions:
      - key: app
        operator: In
        values:
        - noobaa
```

    1.create pvc with label
    2. create vlumegroupsnapshot with matchExpression as selector
    3. verify volumegroupsnahot is created
    

    failed to create volumegroupsnapshot

    volumegroupsnapshot should be created successfully.
