WebRTC: The missing codelab Overview

The overview is an integral part of the Codelab Walk-through. It is split as a separate module for two reasons:

  1. To make it open and available for everyone without the need to enroll to the codelab course
  2. Because it covers the preparation needed before we can start digging into the code
