The image's canonical reference is a name with a digest of the image's manifest, so compute and return that value as the image's reference in ImageStatus() and in ContainerStatus(). We don't auto-store a name based on the image digest when we pull one by tag, but then CRI doesn't need us to do that. Signed-off-by: Nalin Dahyabhai <nalin@redhat.com>
