Kong Operator does not support Control Plane Groups

[damian-kong]

Current Behavior

If I create a Control Plane Group using the KonnectGatewayControlPlane CRD with cluster_type: CLUSTER_TYPE_CONTROL_PLANE_GROUP, and then attach member control planes to it (as explained here https://developer.konghq.com/operator/konnect/crd/control-planes/control-plane-group/)

kind: KonnectGatewayControlPlane
apiVersion: konnect.konghq.com/v1alpha2
metadata:
  name: control-plane-group
  namespace: kong
spec:
  createControlPlaneRequest:
    name: control-plane-group
    cluster_type: CLUSTER_TYPE_CONTROL_PLANE_GROUP
  members:
  - name: gateway-control-plane
  konnect:
    authRef:
      name: konnect-api-auth

I get the error:
KonnectExtension.konnect.konghq.com "my-konnect-config" is invalid: status.konnect.clusterType: Unsupported value: "": supported values: "ControlPlane", "K8SIngressController"

However the clusterType of my-konnect-config is not "", it's "CLUSTER_TYPE_CONTROL_PLANE_GROUP" which is not in the supported values.

The KonnectExtension itself can reference to a KonnectGatewayControlPlane (which could be a standard control plane or a group), but the docs don't confirm that a KonnectExtension can directly target a Control Plane Group type KonnectGatewayControlPlane for DataPlane attachment.

Expected Behaviour

The KonnectExtension can reference to a KonnectGatewayControlPlane with cluster_type: CLUSTER_TYPE_CONTROL_PLANE_GROUP

Operator Version

Tested on Kong Operator version 2.1
