Calling reconciler.SetupWithManager with .For() multiple times loses previous apiTypes with controller-runtime < 0.7.0 or raises error with newer controller-runtime

[yaksharma]

Expected Behaviour

Kratos controller-runtime consumer should watch both scalingv1alpha1.Kratos and corev1.ConfigMap resources for kratos spec.

Actual Behaviour

Kratos controller-runtime consumer calls [.For(scalingv1alpha1.Kratos).For(corev1.ConfigMap](https://github.com/adobe/kratos/blob/master/controllers/kratos_controller.go#L89-L90)), then scalingv1alpha1.Kratos is silently lost in favour of ConfigMap. with controller-runtime < 0.7.0 or raises an error for newer versions.

Reproduce Scenario (including but not limited to)

• Please see (#1173)
• An error is added for this behavior with (#1176)
• As a workaround, to watch multiple apiTypes consumer can use .Watches() or . Owns() instead, alternatively limit the use of For to one apiType.

Steps to Reproduce

• Run Kratos operator against latest kind cluster

Platform and Version

• controller-runtime v0.9.2
• kind version 0.11.1

Sample Code that illustrates the problem

https://github.com/adobe/kratos/blob/master/controllers/kratos_controller.go#L89-L90

func (r *KratosReconciler) SetupWithManager(mgr ctrl.Manager) error {
	return ctrl.NewControllerManagedBy(mgr).
		For(&scalingv1alpha1.Kratos{}).
		For(&corev1.ConfigMap{}).
		Complete(r)
}
