Use static ip addresses for containers and centralize the proxy components in a single file.

I had to use static ip addresses here due to a very anoying NGINX
behavior which is: `nginx: [emerg] host not found in upstream
"companion:8081" in /etc/nginx/nginx.conf:17`

NIGNX will NOT start if it can't find the container IP address from the
Docker DNS resolver 127.0.0.11 which is pretty fucking anoying. Thanks
nginx dev for that stupid design.
