Expose metrics on different port, different express app.

```js

const express = require('express');

const promExpress = require('prometheus-express');

const mainApp = express();

mainApp.use(promExpress.instrumentExpress({exposeMetrics: false}));

mainApp.listen(3000, (e) => {

    console.log('listening on a friendly 3000 port serving public traffic');

});

const metricsApp = express();

metricsApp.use(promExpress.exposeMetrics());

metricsApp.listen(3001, (e) => {

    console.log('exposing metrics for mainApp on port 3001, which isn\'t serving public traffic');

});

```
