msecs{number}callback{Function}- Returns: {http2.Http2ServerRequest}
Sets the [Http2Stream][]’s timeout value to msecs. If a callback is
provided, then it is added as a listener on the 'timeout' event on
the response object.
If no 'timeout' listener is added to the request, the response, or
the server, then [Http2Stream][]s are destroyed when they time out. If a
handler is assigned to the request, the response, or the server’s 'timeout'
events, timed out sockets must be handled explicitly.
