Temporarily pull machine images from side repo
Until podman4 is in the fcos trees, we need to pull the machine images from a side repository. There is a hard coded bit that forces the side repo download right now. Simple comment or removal of the bit will revert to normal download behavior. [NO NEW TESTS NEEDED] Signed-off-by: Brent Baude <bbaude@redhat.com>
