Code Issues Proposed changes

Add image type capability flags and trait conversions

Browse Source 
This makes the base virt driver define capability flags for each of the
glance-defined image types. It also adds a capability-to-trait mapping
for each, causing any driver that supports a given image type to expose
the corresponding trait.
