Return return express server instead of express

[jasperblues]

Given the following:

    util.options.set(options);

    var rawConfigs = loader.load(options.configDir);

    var configs = defaults.assignToAll(rawConfigs);

    var app = initExpress(options.port, options.https);

    registerServices(app, options, configs);

    return app;

};

If we returned instead:

var initExpress = function(port, secureOptions) {

    var app = express();

    if(secureOptions) {
        const server = https.createServer(secureOptions, app).listen(port);
    } else {
        const server = app.listen(port);
    }

    return server;
};```

^-- if we returned server from above, it would be possible to close programmatically, eg for specs (I created specs to prove each fake endpoint works, since they were slightly complex).

You can use your own instance of express, and install the dyson middleware onto that, as shown the second example at https://github.com/webpro/dyson#custom-middleware. That's what you're after, right?
