Azat Khuzhin 2a2f858365 Significantly reduce memory usage in AggregatingInOrderTransform 
Clean the aggregates pools (Arena's objects) between flushes, this will
reduce memory usage significantly (since Arena is not intended for
memory reuse in the already full Chunk's)

Before this patch you cannot run SELECT FROM huge_table GROUP BY
primary_key SETTINGS optimize_aggregation_in_order=1 (and the whole
point of optimize_aggregation_in_order got lost), while after, this
should be possible.
