Add a force pipelining option to load flags.

Details:
- Add a HttpPipelinedHostForced class for connections with forced requests.
  + Forced requests get their own pipeline and there's only one per host.
  + They always try to pipeline and won't retry if evicted.
  + Only one HttpStreamFactoryImpl::Job runs for all requests to the same
    origin with forced pipelining. All requests will fail if that Job fails.
- Track HttpPipelinedHosts with a Key. Right now that's origin and
  force-pipelining, but it might be expanded to include content type.
- Add a BufferedWriteStreamSocket that wraps a normal socket. It buffers Write()
  calls until a task fires to dispatch the buffer to the underlying socket.
