Firefox OS/Performance/Using Docker to Ease Debugging Firefox OS

Proposal

1. Set up private Docker Registry. 2. Configure a Docker image for building B2G from source on every commit. 2.1. Create a Jenkin's task to drive the docker daemon to update code, do the build, and snapshot the docker image into the registry. 3. Write docs for Windows/Mac users on setting up a VM to run docker images. 4. Write docs for Linux users on running docker images. 5. Update bisection doc on how to grab the right docker image and flash a phone with the results.
