Ingress-nginx is now deprecated, so we changed ingress management:
- traefik is now the default ingress class to use
- we add traefik ingressroute management too

     Declare an ingress rule for the service. The port should be exposed or
     declared with {{ printf "%s/%s" .KatenaryPrefix "ports" }}.

+    The default ingress class is "traefik".

+    **Files generated:** Both `ingress.yaml` (standard Kubernetes Ingress) and
+    `ingressroute.yaml` (Traefik IngressRoute CRD) are generated. You can

+    - `ingress.ingressRouteEnabled` - controls IngressRoute installation
+
+    Setting `type: ingressroute` automatically sets `ingressRouteEnabled: true`.
