> Provide timeline view in Job and Stage UI pages

>                 Key: SPARK-3468
>                 URL:
>             Project: Spark
>          Issue Type: Sub-task
>          Components: Web UI
>    Affects Versions: 1.4.0
>            Reporter: Kousuke Saruta

> I sometimes trouble-shoot and analyse the cause of long time spending job.
> At the time, I find the stages which spends long time or fails, then I find the tasks
which spends long time or fails, next I analyse the proportion of each phase in a task.
> Another case, I find executors which spends long time for running a task and analyse
the details of a task.
> In such situation, I think it's helpful to visualize timeline view of stages / tasks
/ executors and visualize details of proportion of activity for each task.
> Now I'm developing prototypes like captures I attached.
> I'll integrate these viewer into WebUI.
