[Feature Request] add batch option to `td job:result` and `td query`.

This idea comes from MySQL's batch mode. That mode print the results using tab as the column separator, with each row on a new line.

This feature is very useful when copying the result and past it to Microsoft Excel or some applications.

for example:

````
$ bin/td query -d testdb -B -w "select v['code'] as code, count(1) as cnt from www_access group by v['code']"

 ----------------------------------------------------------------
  MapReduce time taken: 22.501 seconds
  Time taken: 22.782 seconds
Status     : success
Result     :

404	17
500	2
200	4981

````

also I think changing `format` option is good solution too.  It is better to print other format if it enable without `output` option.


Thanks,
