@hiroppy wanna file a PR or should we pick it up?

Picking this up:
Lets track progress on checkboxes:

• sockPort: docs(config) document devServer sockPort option #2995
• injectClient: docs(config) document devServer options injectClient and injectHot #2996
• injectHot: docs(config) document devServer options injectClient and injectHot #2996

I still have no idea what these do though, even with the documentation

Agreed @IronSean. I just ran into an issue getting a library working with webpack-dev-server and ran into the injectClient following the thread for webpack/webpack-dev-server#2484. As it turns it, it seems to have fixed the problem I was running into by setting this to false but I have no idea why really. Better documentation here would most likely help.
