#4306 raised an issue in our initial integration with urllib3's InvalidHeader implementation. We've been leaking an unwrapped exception in some occasions through our HTTPAdapter. This patch should consolidate to the single Requests exception in all cases.
This may technically be considered breaking as we're changing the exception type, but Requests
InvalidHeaderwas already raised through this API in the common case, so I would consider this as more of a bug.
