Add Volume Type to Horizon Instance Creation Workflow

[James Black]

This is a Wishlist item.

Currently when a user is creating an instance and under the source menu - they cannot choose volume type for the instance. A volume needs to be created first under the Volumes tab, then selecting Volume Source "Image" and Type etc from the drop down.

It would be less confusing for end users if they had the option to accomplish this from the Instance creation menu, rather than have to complete steps in two different locations. Perhaps with a Drop Down menu between Select Boot Source and Volume Size (GB) *. Perhaps the Drop Down could query available volume_type backends so whatever is available would display in the list.

Specifying Volume Type via the API with microversion 2.67 >= works, it would be nice if Horizon also could accomplish this too.

Thanks.
