* cmd/k8s-operator/deploy: deploy a Tailscale IngressClass resource. Some Ingress validating webhooks reject Ingresses with .spec.ingressClassName for which there is no matching IngressClass. Additionally, validate that the expected IngressClass is present, when parsing a tailscale `Ingress`. We currently do not utilize the IngressClass, however we might in the future at which point we might start requiring that the right class for this controller instance actually exists.
