LimitSubqueryOutputWalker
class LimitSubqueryOutputWalker extends SqlWalker
Wraps the query in order to select root entity IDs for pagination.
Given a DQL like SELECT u FROM User u it will generate an SQL query like:
SELECT DISTINCT
Works with composite keys but cannot deal with queries that have multiple
root entities (e.g. SELECT f, b from Foo, Bar)
