Test to verify fstype specified in storage-class is being honored after volume creation.
Steps
1. Create StorageClass with fstype set to valid type (default case included).
2. Create PVC which uses the StorageClass created in step 1.
3. Wait for PV to be provisioned.
4. Wait for PVC's status to become Bound.
5. Create pod using PVC on specific node.
6. Wait for Disk to be attached to the node.
7. Execute command in the pod to get fstype.
8. Delete pod and Wait for Volume Disk to be detached from the Node.
9. Delete PVC, PV and Storage Class.
