cmd/k8s-operator,k8s-operator: proxy configuration mechanism via a new ProxyClass custom resource (#11074) * cmd/k8s-operator,k8s-operator: introduce proxy configuration mechanism via ProxyClass custom resource. ProxyClass custom resource can be used to specify customizations for the proxy resources created by the operator. Add a reconciler that validates ProxyClass resources and sets a Ready condition to True or False with a corresponding reason and message. This is required because some fields (labels and annotations) require complex validations that cannot be performed at custom resource apply time. Reconcilers that use the ProxyClass to configure proxy resources are expected to verify that the ProxyClass is Ready and not proceed with resource creation if configuration from a ProxyClass that is not yet Ready is required. If a tailscale ingress/egress Service is annotated with a tailscale.com/proxy-class annotation, look up the corresponding ProxyClass and, if it is Ready, apply the configuration from the ProxyClass to the proxy's StatefulSet. If a tailscale Ingress has a tailscale.com/proxy-class annotation and the referenced ProxyClass custom resource is available and Ready, apply configuration from the ProxyClass to the proxy resources that will be created for the Ingress. Add a new .proxyClass field to the Connector spec. If connector.spec.proxyClass is set to a ProxyClass that is available and Ready, apply configuration from the ProxyClass to the proxy resources created for the Connector. Ensure that when Helm chart is packaged, the ProxyClass yaml is added to chart templates. Ensure that static manifest generator adds ProxyClass yaml to operator.yaml.
