> I have another thought, which is to rename the time interval related windows. Currently, we have 3 types of time interval window:
>  {{TimeWindow}} -> to have {{[start,end)}} time interval
>  {{SessionWindow}} -> to have {{[start,end]}} time interval
>  {{UnlimitedWindow}} -> to have {{[start, MAX_VALUE)}} time interval
> I think the name {{SessionWindow}} is definitely not good here, especially we want to use it in {{SlidingWindows}} now, although it is only used for {{SessionWindows}} before. We should name them with time interval meaning, not the streaming window functions meaning. {{}}Because these 3 window types are internal use only, it is safe to rename them.

> {{TimeWindow}} --> {{InclusiveExclusiveWindow}}
>  {{SessionWindow}} / {{SlidingWindow}} --> {{InclusiveInclusiveWindow}}
>  {{UnlimitedWindow}} --> {{InclusiveUnboundedWindow}}
