[STORM-2686] Add Locality Aware Shuffle Grouping
see: https://issues.apache.org/jira/browse/STORM-2686
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.
