    [STORM-2686] Add Locality Aware Shuffle Grouping

    We want to add a locality aware shuffle grouping to favor the target tasks 
in closest network distance.  
    Currently the network distance is some hard coded values like: 
WORKER_LOCAL, HOST_LCOAL, RACK_LOCAL, and UNKNOWN (everything else). Further 
improvement could be using ping times between supervisors.
    I am doing more integration testing and performance testing.
