How to Test the new Google Tag Manager Integration

1) ssh into your docker VM: `vagrant ssh docker`

2) execute `docker pull tziel/edx-lite:aspen-1.01` (I uploaded a working image to the Docker Hub)
3) in http://launcher.dev/admin/deployment/project/  -> `open edx lite` update the image name to `tziel/edx-lite:aspen-1.01` AND also add a new env var (add space after the Mandrill key and paste this: `GOOGLE_TAG_MANAGER_ID=GTM-MBDCWP`)
4) deploy the updated edX lite project
5) make sure that nothing blocks Google Tag Manager (i.e. cookies, including 3rd party cookies, are on, Ghostery/AdBlock etc. is disabled for *.demo.dev etc.)
6) Open CMS, then open LMS and go to the login page. These are the visible signs of the GTM integration, but Google Analytics is also injected.
