rsritesh d2f91755ab libvirt: flatten rbd images when unshelving an instance ... Previously attempts to remove the shelved snapshot of an unshelved instance when using the rbd backends for both Nova and Glance would fail. This was due to the instance disk being cloned from and still referencing the shelved snapshot image in Glance, blocking any attempt to remove this image later in the unshelve process. After much debate this change attempts to fix this issue by flattening the instance disk while the instance is being spawned as part of an unshelve. For the rbd imagebackend this removes any reference to the shelved snapshot in Glance allowing this image to be removed. For all other imagebackends the call to flatten the image is currently a no-op.
