podman rmi should only untag image if parent of another
podman rmi was deleting an image even if it was a parent of another image. This fix just untags the image instead. This also fixes podman rmi to remove intermediate images of an image when the image is removed. Signed-off-by: umohnani8 <umohnani@redhat.com> Closes: #1055 Approved by: mheon
