Use ingress to manages external access to services within a cluster

Attempt to setup ingress which is already provided in the charts to provide
access to the openQA services. Only of the advantages is that can expose the
services under the same IP, as opposed to NodePort which can only have one
service per port.

* Replace traefik with nginx
* prevent openqa-webui start too soon and before db
* set the baseurl to openqa.example.com
