Those are essentially the steps as I remember them too.  Sean changed 
the dependencies in the blueprints so the nova glance v2 blueprint is 
the root dependency, then multiple images and then the other download 
handler blueprints at the top.  I haven't checked but the blueprints 
should be marked as not complete (not sure what that would be now) and 
marked for next, the v2 glance root blueprint should be marked as high 
priority too so we get the proper focus when Juno opens up.
