Comment 7 for bug 1320090

Hi Robert! We've approved a spec https://review.openstack.org/#/c/95701/ one part of which is moving all temporary variables from driver_info to instance_info, with the latter being cleaned unconditionally every time. https://review.openstack.org/#/c/94855/ is responsible for this. I'm assigning Lucas, as he's the one who works on that patch.
