Heads Up: Netbox Docker changes how HTTP content is served

[cimnine]

I would like to inform you that we will change how Netbox Docker server HTTP traffic in the next version.
Instead of nginx serving static content and forwarding all dynamic content to gunicorn, we'll be using Nginx Unit to do both.

This means one less container and should overall simplify the deployment.

Please see netbox-community/netbox-docker#361 for reference.
