configurable hostname for sockjs-node

https://github.com/facebookincubator/create-react-app/blob/master/packages/react-dev-utils/webpackHotDevClient.js#L61-L69 as shown in this file there is no way to config hostname and everything about this sockjs-node ajax request. is there any reason for it that there is no configuration for it ?

I`m working on a product which is not spa. uses cookie sessions and there is no authentication token obviously. so I was in need of hot reload to. I load my react app inside the main app and for the hot reload I did change the source code of webpackHotDevClient to what I want in order to make /sockjs-node/info ajax works. without changing this config /sockjs-node/info hits http://app.dev/sockjs-node/info but I want it to hit on http://localhost:3000/sockjs-node/info.

var connection = new SockJS(
  url.format({
    protocol: "http",
    hostname: "localhost",
    port: "3000",
    // Hardcoded in WebpackDevServer
    pathname: '/sockjs-node',
  })
);

after this change things are working fines with hot reload on

react-dev-utils may be an internal package for create-react-app but i highly recommend to make it configurable. I believe that many people would use this project for reference and make their own configs, just like me 😃

I fixed this problem in this PR #1994 but it never got merged, there was a lot of discussion about a better solution but I was never entirely sure what the better solution was. Would love to get this fixed.
