node-http2: http2 agent doesn't work with request module

Hi,

I’m trying to use the http2 agent with the request module. Running

var request = require("request");
var https = require("https");
var myHttp1Agent = new https.Agent({ca:ca});
request({url:"https://foo.testing/", agent:myHttp1Agent},function(error, response, body){
  console.log("request with http1 agent");
  console.log(error,body);
});

works fine but with the http2 version

var request = require("request");
var http2 = require("http2");
var myHttp2Agent = new http2.Agent({ca:ca});
request({url:"https://foo.testing/", agent:myHttp2Agent},function(error, response, body){
  console.log("request with http2 agent");
  console.log(error,body);
});

I get an exception:

_http_client.js:137
    self.agent.addRequest(self, options);
               ^

TypeError: self.agent.addRequest is not a function

    at Immediate._onImmediate (/home/node/app/node_modules/request/request.js:588:7)
    at processImmediate [as _immediateCallback] (timers.js:383:17)

As far as I understood, http2 is supposed to be a drop in replacement for the http(s) module. So, is this a bug?
