I'm unsure wheter or not this change requires a changelog. For the moment, I marked it as [chore] as it does not touch a component that is ending up in production. Furthermore, consumer/consumertest is also not a listed component in .chloggen/config.yaml.

If you want to see a changelog, I'm happy to apply - please let me know.

This changes a public API. So it needs a changelog entry.
I've opened a PR adding a metadata.yaml to the package. #14252
