disable reviewable for kubernetes repos that don't use it

[spiffxp]

Discussion here: https://groups.google.com/forum/#!topic/kubernetes-dev/0RhWYvxW2XI

https://reviewable.kubernetes.io/repositories claims it's enabled for

• kubernetes/client-go (doesn't make sense, PR's to this repo aren't accepted)
• kubernetes/contrib
• kubernetes/frakti
• kubernetes/gengo
• kubernetes/git-sync
• kubernetes/heapster
• kubernetes/helm (no webhook)
• kubernetes/ingress-nginx
• kubernetes/k8s.io
• kubernetes/kops (webhook is disabled)
• kubernetes/kube-state-metrics
• kubernetes/kubernetes (all webhook deliveries are erroring)
• kubernetes/node-problem-detector
• kubernetes/test-infra (webhook is disabled)
• kubernetes/website (webhook is disabled)

I heard objections to disabling reviewable for kubernetes/kubernetes, so I will leave that enabled. But I'm not actually sure it's properly hooked up given the webhook errors.

Based on this query of PR's, gengo also recently used a reviewable review. Other uses of reviewable date back to Oct 2017.

I used the reviewable UI at https://reviewable.kubernetes.io/repositories to disable reviewable for all repos, except for:

• kubernetes/gengo
• kubernetes/kubernetes (shows "repository not found" error through the ui)

I probably need @thockin's help to troubleshoot why it's not working for k/k if there is a desire to use it there. I'm guessing it must have stopped working a few months back and we just never noticed.

I disabled the integration for all. Given that it wasn't working, I have a hard time claiming it is needed.
