I don't see this used anywhere in the controller logic, can you explain what's the role of this field? Is this something that's in the latest OCI spec but not implemented by any registry yet?

This is just a quick rebase of a WIP branch that I had from around the time of #1244. I thought I should open a draft PR before it's forgotten. It still needs some tidying for sure. This field looks like an idea I had at the time, I'll refresh my memory and see if this needs implementing or deleting.

I have recapped this. The idea is actaully that media type of artifact index and the layers that it points at are two distinct notions. I should probably try implementing the field in this PR, without flipping API semanitcs until there is more to make a case for API version bump.
The point is that what you want to select primarily is the media type of the OCI index, the type of the blob is a secondary concern, it can be defaulted to a tarball.

This change makes fetching of OCI artifacts compatible with a wider range of images, namely where the top-level object is an index. Once the index is fetched, the media type selector and (optionally) a numeric offset will be applied to determine what blob to use.
Towards #1247.
