af660140c3 Do only merging of sorted blocks on initiator with distributed_group_by_no_merge=2 
When distributed_group_by_no_merge=2 is used (or when
optimize_distributed_group_by_sharding_key takes place), remote servers
will do full ORDER BY, so initiator can skip this step and do only merge
of ordered blocks.
