Show N rows only -Listing Enhancement request

[vaithu]

I'm trying to show always 50 rows only in the grid and using the below code

listing = Components.listing.properties(StarZeroLevel.PROPERTY_SET)
                .dataSource(datastore,StarZeroLevel.TARGET)
                .pageSize(50)
                .withQueryConfigurationProvider(this::queryFilter)

This code doesn't restrict the number of items instead just read 50 rows at a time. I see there is a way to do it using Query Statement's limit() method, but I do not see any way to use in Component's Listing. Again, looks this is possible if I use Vaadin DataProvider callbacks method instead of DatastoreDataProvider but I want to go with 100% holon platform code.
