This PR adds the ability to do a limited number of retries (3) for end2end tests. Often the windows tests will fail during CI (an error about the event loop being closed) crashing the whole end2end ci pipeline.
As these are flaky, not broken, re-running the failed tests often fixes the problem. But this is annoying to have to get and email and click re-run each time it happens. This new version will rerun failed tests automatically, logging when a test that passed needed multiple tires. Hopefully this makes the windows issue less annoying going forward.
Related to #249, need to verify the retries work/make windows more reliable before we close it.
