Allow podman push to push manifest lists

When doing a podman images, manifests lists look just like images, so
it is logical that users would assume that they can just podman push them
to a registry.  The problem is we throw out weird errors when this happens
and users need to somehow figure out this is a manifest list rather then
an image, and frankly the user will not understand the difference.

This PR will make podman push just do the right thing, by failing over and
attempting to push the manifest if it fails to push the image.

Fix up handling of manifest push

Protocol should bring back a digest string, which can either be
printed or stored in a file.

We should not reimplement the manifest push setup code in the tunnel
code but take advantage of the api path, to make sure remote and local
work the same way.
