Ansible machine running NGINX and load-balancing to Guac server
Since Guac coming up depends on Ansible, Guac creates the NGINX configuration and populates with its own IP and then copies the config to the Ansible machine and restarts NGINX
DNS for Guac points to VIP on NGINX and is tracked via Dynamic DNS
Squid proxy running on Ansible machine provides outbound access for Guac and TetData
Docs changed to show TetData configuration of proxy server (Lab 5)
