> Throughput is a fundamental metric to reasoning about the performance bottleneck of a topology. Displaying the throughputs of components and tasks on the web ui could greatly facilitate the user identifying the performance bottleneck and checking whether the the workload among components and tasks are balanced. 
> What to do:
> 1. Measure the throughput of each spout/bolt.
> 2. Display the throughput metrics on web UI.
