kube-janitor in production clusters

[dneuhaeuser-zalando]

Please consider deploying kube-janitor to production clusters.

We have an locust based load test, that we sometimes temporarily deploy to perform load tests. We have a separate one to ensure SLOs are being met that terminates but this one is deployed with the web interface to try out different configurations.

Due to misconfiguration of the deployment pipeline, it got accidentally deployed due to a dependency update and ran in production for some time until discovered by accident. Given the resources requested, this was quite a bit of money wasted. We've fixed the configuration of the pipeline but I would feel even more comfortable only having this around temporarily via kube-janitor.

SGTM, we should just make sure that it does not do "more than it should" and that the additional API requests do not cause impact.

Does it support select by namespace?
Then you can opt-in by deploy to your namespace.
