Docker Support

Specifically I need Labels for ansible playbook bundles (APB) in order to determine dependencies and other information. If Layers is not currently stored, those are necessary as well.

Consider registry.access.redhat.com/openshift3/mediawiki-apb:latest

% skopeo-inspect docker://registry.access.redhat.com/openshift3/mediawiki-apb:latest
