We would like to think about removing composer from RHEL9 & RHEL10.

A possible approach could be to create a thin wrapper around `image-builder-cli` with a RESTAPI that could stand-in for the existing `cloudapi` in composer.

This would allow us to simplify and remove what we don't need from the composer project.

Some considerations to make:

• possible re-use of the json store in osbuild-composer so we can cleanly obsolete composer
• we could possibly re-use the existing weldr  tests to validate this approach
