My concern is how much else where assumes nova is working with the 
glance v2 API because there was a nova blueprint [1] to make nova work 
with the glance V2 API but that never landed in Icehouse, so I'm worried 
about wack-a-mole type problems here, especially since there is no 
tempest coverage for testing multiple image location support via nova.
