'Bearer' gets stripped from 'Authorization' headers

[gverm]

Using the delegates system, I am doing a request to a different service in authorize(). I am accessing the 'Authorization' header like this: context['request_headers']['Authorization']. I noticed I was getting malformed header errors back from my service and that it seemed that 'Bearer' is stripped from the 'Authorization' headers. Printing them confirmed this suspicion. This is preventing me from just passing the request 'Authorization' headers to my other service.
