We are testing bouncer, a redirection service. So when making bouncer

requests, don't automatically traverse the first level of possible redirects,
but catch it and then follow it.

This way, if what we are being redirected to fails, that's what we'll report
on. Otherwise, this obscures what URL is failing/timing-out

This is not beautiful Python, my apologies, and I am sure it could be implemented more cleanly and generically. But as-is, this would at least allow pinpointing if it's bouncer or one of our CDNs causing the production Jenkins job to fail intermittently.
