This version aims to have Colab with a new plugable architecture. Main goal is to allow a user to just enable/disable proxied apps by adding/removing it from INSTALLED_APPS.

Once the app is installed it's resources should be automatically connected to search, stats (metrics) and it's links should be exposed at the navbar.

For now the code of proxied apps will live in the directory proxy/[appname] but ideally those apps will be shipped in individual Django projects.
