> Today when we group processor nodes into groups (i.e. sub-topologies), we 
> assign the sub-topology id for global tables' dummy groups as well. As a 
> result, the subtopology ids (and hence task ids) are not consecutive anymore. 
> This is quite confusing for users trouble shooting and debugging; in 
> addition, the node group for global stores are not useful as well: we simply 
> exclude it in all the caller functions of makeNodeGroups.
> It would be better to simply exclude the global store's node groups in this 
> function so that the subtopology ids and task ids are consecutive.
