capability to use AGIC with AKSARC enabled Clusters --> AzureStack HCI

[chris8205]

enhance the AGIC to add the possibility to redirect the traffic to a existing ingress service ip inside a onPrem AKSARC // AzureStack HCI AKS(ARC)

something like this...

agic.hybrid.enable: true
agic.hybrid.ingressClassName: ingressClassName (nginx-ingress)
agic.hybrid.ingressPublicIP: [PublicIP of the ingress]

if hyrid enabled, agic works similar but takes ingress information from k8s-ingress with this specific ingressClassName and tells the azure agw to redirect all traffic to the configured publicIP...
TLS Certs and probes are pushed like before from the k8s-ingress config into the azure-agw
