The puller --platform flag doesn't support platform variants about containerregistry HOT 3 CLOSED

Looking at the OCI spec (and what is implemented in client/v2_2/docker_image_list_.py) we may also need to support os.features, os.version, and probably features too. (The golang image uses os.version for the windows images, for example.)

I'm not sure what the cleanest way to do this is. I don't think we can really add all of those fields to --platform in a manageable way, though.

@ixdy afaik rules_docker is the main user of this repo, so breaking changes (as long as we follow up with PR in rules_docker) should be fine. My preference is option 1.

@ixdy if you want one flag to fit all of this in, you could change --platform to accept a json blob and just pass that through to resolve, though for interactive use that is probably more cumbersome than --os and --architecture flags (et al).
