Domain Reliability: Don't send proxy address, other fixes

Make sure the monitor does not collect the proxy's address if one was used.
(In the process, refactor RequestInfo to contain the whole HttpResponseInfo,
tighten up OnRequestLegComplete, and poke at unittests a bit.)

Also, count network errors as well as HTTP errors as failures (!).
