CONTROLLER_ENABLE_CONTROLLER_INGRESS_CLASS_NETWORKINGV1 not disabled when KIC is Namespaced

[jasiek-zywczak]

When running KIC in the namespaced mode we need to disable cluster scoped permissions. Unfortunately despite the fact documentation mention that watching ingressClass should be disabled in this situation, charts does not properly handle this. https://github.com/Kong/charts/tree/main/charts/kong#removing-cluster-scoped-permissions

charts/charts/kong/templates/_helpers.tpl

Line 372 in e9c77a5

{{- $_ := set $autoEnv "CONTROLLER_ENABLE_CONTROLLER_KONGCLUSTERPLUGIN" false -}}

there is a bug in KIC itself Kong/kubernetes-ingress-controller#2712 even enabling this flag might not be enough :(

Closing since this is handled somewhere between Kong/kubernetes-ingress-controller#2724 and #611
