Using proxy from webpack-dev-server

Created by: SpaceK33z

Something I noticed while being bored and looking through scripts/start.js: CRA handles proxy themselves, but webpack-dev-server also has built-in support for this (using the same package, http-proxy-middleware).

As I maintain WDS, I wonder what is missing from the proxy functionality in WDS. Feedback is welcome :). We only use the powerful http-proxy-middleware package since a few weeks, so maybe it was a better decision back then?
