Triage Crawler exceptions: Maven 403s

When triaging, make sure to identify whether this issue should or shouldn't be happening -- if it's not truly exceptional, try to convert to a less interesting tracing method (e.g. a warning trace).

looking into these: they are valid requests that we are making, the packages/files exist. I believe the 403's are due to us being throttled/blocked by maven for not following their robots policy.

Either way, these should just be logged as a crawl error, not exception.

Of course, like others we are only getting this at ghcrawler/lib/crawler.js:132, need to come up with a solution for all these.
