No Graceful Shutdown?

[alistair-hmh]

Expected behavior

Proxy closes when the parent process receives SIGINT or exit.

Actual behavior

Proxy keeps running

Setup

• http-proxy-middleware: 0.18.0
• server: express 4.16.3

proxy middleware configuration

const options = {
    target: 'http://localhost:3001',
    changeOrigin: true,
    ws: true
};

const appProxy = proxy(options);

server mounting

var app = express();

app.use('/', appProxy);
app.listen(3000);

Using this config, kill the app. The middleware proxy will keep running.

I think the issue is that there needs to be a way to expose proxy.close(). I will try to PR and see if that does it. Right now I can use the express-dynamic-middleware to handle basic routes, but it will not close the websocket proxy unless you call proxy.close(). See: https://github.com/nodejitsu/node-http-proxy#shutdown for the details.
