Include the layout spec if/when this becomes and OCI Project #20

image-spec's image-layout is extremely similar to a special case of ref-engine discovery. I've stubbed out an image-spec branch to demonstrate this, which makes for a more compact and powerful layout spec (although it now depends on the additional ref-engine discovery wording from this repo). If this project, or something like it, ends up in an OCI Project, I recommend we move the layout spec out of image-spec and into this project (unless this project ends up being merged with image-spec).

One of the examples of increased power is the ability to shard the blob store (opencontainers/image-spec#449).

Layout is part of image, branch 1 seems to only explain contents inside image package, but not mentioned anything about discovery mechanism. I think it is much more helpful to discovery by landing it in image-spec master. With it inside image-spec, discovery can go on depended on a canonical protocol template. If it is just landed in discovery, we have only internal canonicalization.

And, I think it is very possible and soon to land branch 1. If it is in this project, it will be so long time to be landed to OCI canonicalization.

I don't think there's any chance of that branch landing in image-spec before the refEngines and casEngines definitions are part of an OCI Project.

And I'd rather avoid a dependency cycle. If there is a separate discovery Project, it should depend on image-spec, and not image-spec component should depend on any discovery components.

If image-spec is hard to accept it currently, it is no problem to land it to this project.
