The idea:
- all nodes generate their config in /etc/nginx/node.conf.d/HOSTNAME.conf
- a python script can read all configs and merge them into one and reload nginx
- using entr in Procfile, anytime any of these config change, they are merged immediately
- the default nginx reload on notify is being removed to prevent from reloading twice
This changes the base-image to the official nginx image,
reducing the virtual size of the image by approx 50%.
