Volume dropdown is empty if only Cinder v2 is running

[Yash Bathia]

Currently create_instance workflow only checks if Cinder v1 is enabled before populating volume id choices and volume snapshot id choices in the Launch Instance form. There should be checks to ensure if either Cinder v1 or v2 is enabled before populating the drop-down menu in Launch Instance.
