> It'd be helpful if the catalogd webui can show timeline for processing each 
> batch of HMS events.
>  * In the timeline, show the start/end time of processing each event. Also 
> show the original eventTime of them.
>  * The timeline can be expanded to show the top 10 events that take the 
> longest time to process, or have the longest delay (processTime - eventTime).
>  * Keep the last 100 batches (configurable).
