> In existing Capacity Scheduler behavior, if user doesn't specify capacity of 
> label, queue initialization will be failed. That will cause queue refreshment 
> failed when add a new label to node labels collection and doesn't modify 
> capacity-scheduler.xml.
> With this patch, capacity of labels should be explicitly set if user want to 
> use it. If user doesn't set capacity of some labels, we will treat such 
> labels are unused labels.
