Adds the Dockerfile for building the Skopeo container image on quay.io. Once merged, this image will be built automatically upon any merge into the master branch. The images will live at: quay.io/containers/skopeo:latest quay.io/skopeo/stable:latest I've built an image using this Dockerfile and have pushed it to both repositories if you want to play with that. Once merged, I'll create similar Dockerfiles for quay.io/skopeo/testing and quay.io/skopeo/upstream. Signed-off-by: TomSweeneyRedHat <tsweeney@redhat.com>
