Describe the bug
Trying out open-appsec with Apisix using the documentation.

The documentation states the following command:

helm install open-appsec-apisix openappsec/open-appsec-apisix \
--set rbac.create=true \
--set service.type=LoadBalancer \
--set appsec.persistence.enabled=false \
--set ingress-controller.enabled=true \
--set ingress-controller.config.ingressClass=appsec-apisix \
--set appsec.userEmail="<your-email-address>" \
--set appsec.agentToken= \
--namespace appsec-apisix --create-namespace

The open-appsec-apisix chart has the Apisix apisix-ingress-controller chart as a dependency (called ingress-controller). So ingress-controller.config.ingressClass=appsec-apisix is meant to be handed over to the dependency chart.

Unfortunately, the chart does not have such a parameter. In the chart it is called config.kubernetes.ingressClass:

config:
 [...]
  kubernetes:
    ingressClass: apisix
    defaultIngressClass: false

https://github.com/apache/apisix-helm-chart/blob/master/charts/apisix-ingress-controller/values.yaml#L99

So the helm install command should use --set ingress-controller.config.kubernetes.ingressClass=appsec-apisix to properly set the ingressClass name. Otherwise the ingressClass name will be the apisix-ingress-controller chart's default value apisix.

Kind Regards,
Johannes
