    **Special notes for your reviewer**:
    The default value of --enable-controller-attach-detach is true, map will be initialized like:
    ```
    if kl.enableControllerAttachDetach {
    		if node.Annotations == nil {
    			node.Annotations = make(map[string]string)
    		}
                    ... 
    }
    ```
    if set  --enable-controller-attach-detach to false, map will have no Initialized.
