qemu-iotests: make create_image() common
Both 030 and 041 use create_image(). Move it to iotests.py. Also drop ImageStreamingTestCase since the class now has no methods. Suggested-by: Kevin Wolf <kwolf@redhat.com> Signed-off-by: Stefan Hajnoczi <stefanha@redhat.com> Signed-off-by: Kevin Wolf <kwolf@redhat.com>
