> Enhance the current functionality of Evictor as per this [design
> document|https://docs.google.com/document/d/1Rr7xzlItYqvFXLyyy-Yv0vvw8f29QYAjm5i9E4A_JlU/edit].
> This includes:
> - Allow eviction of elements from the window in any order (not only from the
> beginning). To do this Evictor must go through the list of elements and
> remove the elements that have to be evicted instead of the current approach
> of : returning the count of elements to be removed from beginning.
> - Allow eviction to be done before/after applying the window function.
