DRILL-6180: Use System Option "output_batch_size" for External Sort
External Sort has boot time configuration for output batch size
"drill.exec.sort.external.spill.merge_batch_size" which is defaulted to 16M.
To make batch sizing configuration uniform across all operators, change
this to use new system option that is added
"drill.exec.memory.operator.output_batch_size".
This option has default value of 32M. Changed it to 16M.
