Change subject: IMPALA-5611: KuduPartitionExpr holds onto memory unnecessarily
......................................................................


Patch Set 1:

Thomas, wrt my concern earlier about the hash partitioning case doing the call 
every row, I checked with Tim and he agreed he didn't think we should do that. 
So when you're making the change to DataStreamSender can you move the 
FreeLocalAllocations call for the hash partitioning case down a few lines so 
it's per-batch and not per-row?
