[TEST]#2 Adding new test RPCS/10_create_storagevolume.py
Patch 2:
--------
1) Added code to verify the StoVol template RASD.
2) Seperated the SDC query into a function.
3) Used the default_disk_pool for DIR type pools
This test verifies the creation of StorageVol in the dir pool.
Tested with KVM on F11 with current sources.
