refactor: Switchted from "offical" `haproxy` to `haproxytech/haproxy-debian`

* `haproxy` is the "official" Docker-Image for HAProxy
** It is maintained by the Docker-Team
** Bugfixes are not included as fast as with `haproxytech/haproxy-debian`
** It does not include all features, that are supported by the image,
   that is maintained by HAProxy Technoligies Inc. directly
* `haproxytech/haproxy-debian` is maintained by HAProxy Technoligies Inc.
** It is maintained regularily
** It includes more features - in particular, the *Data Plane API*
