✨ Default QPS to a saner value in and out of tests #365

The default QPS on REST clients is 5 (with burst to 10), which is rather slow. This is especially true when running a test server, since you want to run tests pretty quickly, and the test cluster is default.

For normal clients, we probably want to default to what the KCM defaults to (our situation isn't quite the same, since we actually share the client across controllers, so we should follow up dealing with that at some point). This gives us 20 QPS with burst to 30.

It seems goimports is not happy, please fix.

If you share client across a test, then client-side rate-limitting will
slow down your test drastically.
This defaults the loaded REST Config QPS to 20 (burst 30), which matches
what the kube controller manager has.  The defaults of 5 and 10
(respectively) are pretty slow, especially since they're shared across
multiple controllers.
