SimulatedDelayFetcher lets one configure various per-host delays, and will make hardcoded replies according to those replies. This exists to help run simulations of server behavior with sites of widely various speeds.
delay_map_path is the path to the file describing the delays for each host The format is: foo.com=4;bar.com=42;baz.com=43; (line breaks are permitted) The delays are in milliseconds.
request_log_path will be used to log when each request was received. (Not when it was served).
Asynchronously fetch a URL, set the response headers and stream the contents to fetch and call fetch->Done() when the fetch finishes.
There is an unchecked contract that response_headers are set before the response_writer or callback are used. Caution, several implementations do not satisfy this contract (but should).
TODO(sligocki): GoogleString -> GoogleUrl or at least StringPiece.
TODO(sligocki): Include the URL in the fetch, like the request headers.
