Is the current master branch without any touched able to pass those tests?

Sadly this code is all auto-generated, we can't make manual changes in this code since we won't be able to regenerate it as the Kubernetes API changes.

The right path here is to regenerate the code to use something like feign instead of okhttp. It's a TODO, but if you want to take it on, I'm happy to help guide it.

I'm going to close this PR since we can't merge it. Please let me know if there are more questions.

Thanks
