Added support for rebuilding a volume-backed instance with a different
image. This is achieved by reimaging the boot volume i.e. writing new
image on the boot volume at cinder side.
Previously rebuilding volume-backed instances with same image was
possible but this feature allows rebuilding volume-backed instances
with a different image than the existing one in the boot volume.
This is supported starting from API microversion 2.93.
