Change ClusterRole to allow access to ingresses

Impersonating the controller's service account (`kubectl proxy --port=8080 --as system:serviceaccount:kube-system:kubernetes-pfsense-controller`) I have requested the same resources and while it's accessing `/apis/extensions/v1beta1/ingresses` just fine, I get a 403 when accessing `/apis/networking.k8s.io/v1beta1/ingresses`.

With this change, it resolves fine!
