I support John's membership. He has several important PRs in tools for release qualification testing including one that streamlines prometheus metrics collection.

@howardjohn please describe the non-PR contributions made... stuff like running the long-running burning tests. You can also refer to other PRs and bugs that reference the testing contributions.

Conditional approval by @louiscryan @geeknoid @linsun on additional pieces of documentation. Need @rshriram and @dcberg @smawson approval offline

[howardjohn]

Sure. I have been working a lot on the long running performance tests (https://github.com/istio/tools). I have added multiple tests there so that we can measure the performance of new features like http 1.0, envoy proxy graceful shutdown, external traffic with the Sidecar resource. I have also worked on automation/monitoring of the tests - currently most of the process is pretty manual looking at metrics, but I have added tests that will pull from prometheus (istio/tools#60) and am working on adding alarms.
