    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.

> 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.
> So, what are the implications if default is changed to 32M for external sort ?
> Instead, should we change the output batch size default to 16M for all 
> operators ?
