Add aggregate functions and streams in queryable store

Browse Source 
First, aggregate functions for minimum, maximum, sum and average
have been added to the queryable store API. These can be used
with the query fields, which have been enhanced for this.

Second, an additional stream like API has been added to retrieve
collections to avoid the creation of huge result objects.
