> Background: 
> When we monitor a coordinator job, statistics of historical workflow 
> instances such as running time can be directly visualized.
> But, we lack the ability to monitor historical statistics of coordinator from 
> perspective of  workflow action.For example, running time of a coordinator 
> action is longer than before, but we can't see the exact change tendency of a 
> sepcific workflow action in it。
> Functional optimization: 
> More detailed view of the coordinator’s history can be observed from 
> perspective of  workflow action.Furthermore,  the trend of a workflow action 
> can be shown directly on front-end graph.
