Previously `info/refs`, `upload-pack`, `receive-pack`, and anything that
needed to make an authorization check with Rails would not forward along
the correlation ID injected in the request context. We solve this by
creating the HTTP request with the same context. This adds some
additional memory allocations for each outbound request.
