Subject: [PATCH] experiments-and-demos: New subdir with skopeo2ostree
 Dockerfile

Before I went all in on jigdo I was playing around with doing
a build from `Dockerfile` of something that looked like Atomic Host,
and then importing that build into an ostree repo.

For a lot of reasons, I think this is not the way to go in general
right now, but let's keep this demo around so we can pick
things up back later if we want to (or someone else does).

Closes: #1193
Approved by: jlebon
