Introduce Runtime.pullImageFromReference, call it in Runtime.FromImageReference
FINALLY, (podman load) can pass through an ImageReference directly from loadCmd all the way to pullGoalNamesFromImageReference, making sure not to trigger the docker-like reference parsing heuristics. Signed-off-by: Miloslav Trmač <mitr@redhat.com> Closes: #1176 Approved by: rhatdan
