> The job page will be too slow to open when there are thousands of executor 
> events(added or removed). I found that in ExecutorsTab file, executorIdToData 
> will not remove elements, it will increase all the time. Before this pr, it 
> looks like timeline1.png. After this pr, it looks like timeline2.png(we can 
> set how many events will be displayed)
