Add Boskos CRDs to prow/cluster, and bump Boskos back to latest

[ixdy]

This is a revert of #16260, along with the required config changes so that Boskos hopefully won't crash.

This goes along with #16266, but it shouldn't be necessary to wait for it, since Boskos is not supposed to do anything if the CRDs already exist.

/hold
because I'm still validating these changes (and also we shouldn't merge this late in the day)

Testing this locally in kind, this seems to do the right thing for the CRDs, but it seems like boskos is now failing to start for a different reason:

{"component":"boskos","error":"listen tcp :8080: bind: address already in use","file":"prow/interrupts/interrupts.go:156","func":"k8s.io/test-infra/prow/interrupts.ListenAndServe.func1","level":"info","msg":"Server exited.","time":"2020-02-13T01:31:20Z"}

Something is causing prometheus to serve metrics for rest_client_request_duration_seconds on port 8080. Still investigating...

found it: https://github.com/kubernetes-sigs/controller-runtime/blob/a7c8a93c1cf395974911ef0ece977a7d27b2bf4b/pkg/metrics/listener.go#L24-L26

We definitely can't roll forward without #16270, but I think this change would work otherwise.

[ixdy]

Updated boskos to v20200213-7790e5cec. This includes #16270 and #16271. I think this works.

Yeah saw it, I want us (openshift) to do it first, because there I can see logs if something goes south again. Will lgtm once that was successful

[alvaroaleman]

Yup, works fine with the CRD update. Does bazel do that automatically if you just add the file?

And thanks a lot for taking care here @ixdy

Looks like it isn't crash looping

[ixdy]

Monitoring appears to be working again too.
