This is a function test for Selector-Label Volume Binding Feature
Test verifies volume with the matching label is bounded with the PVC.
Test Steps
----------
1. Create VMDK.
2. Create pv with lable volume-type:ssd, volume path set to vmdk created in previous step, and PersistentVolumeReclaimPolicy is set to Delete.
3. Create PVC (pvc_vvol) with label selector to match with volume-type:vvol
4. Create PVC (pvc_ssd) with label selector to match with volume-type:ssd
5. Wait and verify pvc_ssd is bound with PV.
6. Verify Status of pvc_vvol is still pending.
7. Delete pvc_ssd.
8. verify associated pv is also deleted.
9. delete pvc_vvol
