[2686] ✨ Webpack 4 upgrade

Webpack 4 beta just released and no features/breaking-changes planned for final release. The hardest part for the upgrade is plugins that need to adapt to new hooks system. We have about 1 month time remaining to the final release of webpack and (hopefully) until then all of the webpack plugins used by nuxt.js will be compatible with 4.x.

PR: #2901 - Status: Done
