Sometimes Jenkins CI tests fail because spot instance workers are shut down in the middle. For now, retry the failed tests up to 3 times. I want to find a better method, since retries can mask flaky tests. Ideally, we want to distinguish between communication failures (due to instance shutting down) and test failure (due to exception thrown).
