> Storm provides per-task level metrics which could be huge when topology has a number of tasks. 
> Task level metric is useful for determining load balance between tasks, but it doesn't need to be time-series fashion.
> Before introducing topology level component like TopologyMaster for JStorm, we can utilize SystemBolt to aggregate task level metrics to per-worker level metrics.
> We should provide options and this feature should be turned off by default to keep backward compatibility.
