Fix nova rescue command with image specified
Fix nova rescue command with image specified

There is no --rescue_image_ref cli parameter to nova rescue.  The
actual parameter is just --image.  It looks like rescue_image_ref
is the key passed to the api when it is called directly, but it
does not work on the cli.
