- configures windshaft to publish cartodb_id as the interactivity layer
- gets the default geometry type from the cartodb redis store
- allows tiles to be styled individually
- provides a link to varnish high speed cache
- provides a infowindow endpoint for windshaft
- provides a map_metadata endpoint for windshaft
