* Clean up tests logging This cleans up the travis logs so you can see the failures better. Older tests in tests/ would call log.SetOutput(ioutil.Discard) in a haphazard way. This add log.Discard and put an `init` function in each package's dir (no way to do this globally). The cleanup in tests/ is clear. All plugins also got this init function to have some uniformity and kill any (future) logging there in the tests as well. There is a one-off in pkg/healthcheck because that does log.
