Volume Type Standard and Discoverability

[josephineSei]

Volume Types in OpenStack provide basic instruction, when creating a volume and can result in choosing a specific backend. We should provide a standard of volume types we would like to see in deployments and improve their discoverability upstream. In the end a documentation of a how to enable / use volume types in scs would also improve the visibility of this important feature.

Action Items

• Standard: Define Standard for the naming of volume types #265
• Upstreaming: Upstream work on the discoverability of certain recommended volume type aspects. #449
• Documentation: tbd
