* Change a bunch of info logs back to warning in crawler, since crawlers are typically run in warning mode, to avoid the info log connection spam
* Ensure that the crawler loop ONLY doesn't start when in tests
* Rename the crawler service to crawler_service_no_loop, so defaults can also be tested WITH a loop
* Test crawler loop modes
* Add message when we received state chaged callback
* Add log to indicate crawling has started and how many peers we're crawling
