> When we use Federation, we will have multiple sub-clusters, and some interfaces need to call all clusters to get results, 
> such as getNodes, getNodeToLabels, etc.
> But if the sub-cluster is unavailable when we call the interface, should the interface return the result?
> The current code is to return the result.If the result is returned, the result information is inaccurate; 
> if the result is not returned, it is not user-friendly
> We'd better add a parameter control, the user chooses whether to report an error or return the result.
