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.
