Review internal Traefik network (close some exposed ports; fix new Gateway Timeouts and put networking inside docker-compose.yml)

[fititnt]

Solution to issue #2 broke the routing. Old temporary way without docker-compose.yml forced me to use docker network connect ... a few times like:

This is the current state of networking:

It works, but lets close a few doors binded directly to the host ports and force all the things via traefik.

https://github.com/fititnt/chatops-wg-ia-js-botkit & https://github.com/fititnt/chatops-wg-ia-php-botman needs update to block ports. Later I commit it.
