Use a doubled proxy-logging instead of each middleware handling it
differently (if at all)

Adding a swift.source to wsgi pre_auth funcs and all middleware that makes
subrequests to proxy server.

NOTE: This change will result in a change in the number of proxy logs made for
staticweb, formpost, tempurl, and any other middleware that performs sub
requests (including swauth and SOS).

Please see docs for details.
