Can you updated quic_simple_client_bin.cc too?

Feel free to do in the Final CL if that is easier.

 //
 // Send a POST instead of a GET:
 //   quic_client http://www.google.com --body="this is a POST body" --host=${IP}
 //
 // Append additional headers to the request:
 //   quic_client http://www.google.com  --host=${IP}
 //               --headers="Header-A: 1234; Header-B: 5678"
 //
 // Connect to a host different to the URL being requested:
 //   Get IP address of the www.google.com
