EO Rock-On Experiment

Hello fellow Rockstor admins and developers :slight_smile: I started using Rockstor over this past Christmas holiday. I wanted to try hosting Docker containers with another reverse proxy than the currently implemented HAProxy and needed to rewrite many Rock-ons to work with the jwilder Nginx proxy. I also wrote these Rock-ons so I could use the Docker dns feature. Hopefully, Rockstor Web UI will have a feature to natively support Docker networks in the future.
