During unshelve, instance is spawn with image created by shelve and is deleted just after, instance.image_ref still point to the original instance build image. In qcow2 environment, this is an issue because instance backing file don't match anymore instance.image_ref and during live-migration/resize, target host will fetch image corresponding to instance.image_ref involving instance corruption. This change fetches original image and rebase instance disk on it. This avoid image_ref mismatch and bring back storage benefit to keep common image in cache. If original image is no more available in glance, backing file is merged into disk(flatten), ensuring instance integrity during next live-migration/resize operation.
