Webpack outputs lots of stats by default. It fills console screens and jenkins logs but we never read it. It also takes webpack some time to gather.

We should drop this information.

We'll start with style-only configurations because we have had the foresight to make them all extend one function, which means we can make a single change in webpack-configurator.
Javascript configurations will first need to be aligned and to extend a function (similar to our "extendProdConfiguration", but different because it targets javascript). In the interest of concision, it'll be another request.
