Rich Hagarty cae34cf1a2 Volume Types tab with QOS Specs
This feature adds a new "Volume Types" tab to the Admin-Volumes panel, and
places QOS Specs on the panel. Future check-ins will add further
QOS Spec functionality, such as adding and deleting, etc.

Partially Implements: blueprint cinder-qos-specs
