mock-chronik-client is now its own package and will move to `modules/`
Going forward, we will get this same workflow of mcc testing but the workflow will be different for mock-chronik-client diffs.
1. Make change to mock-chronik-client
2. Publish an rc version of mock-chronik-client
3. Install this version in all repos that use it
4. Push up diff -- CI will run in all impacted repos
5. If it passes, back out the rc installs in impacted repos
6. Land mcc diff which will auto-publish
7. Now you can install this latest version in repos that need it
This is 'more' to do but I think worth the tradeoff to get this as a published repo.
