 Review comment:
   This part code was only for **PK chunking**. We don't need 2nd level 
PK-chunking any more. (if we have normal pre-partition, we should not use pk 
chunking. It burns out request quota)
   
   I create separate function - getQueryResultIdsPkChunking for pkchunking. and 
made it not to depends on class member this.pkChunking, therefore removed 
pkChunking.

> In SFDC(salesforce) connector, we have partitioning mechanisms to split a 
> giant query to multiple sub queries. There are 3 mechanisms:
>  * simple partition (equally split by time)
>  * dynamic pre-partition (generate histogram and split by row numbers)
>  * user specified partition (set up time range in job file)
> However there are tables like Task and Contract are failing time to time to 
> fetch full data.
> We may want to utilize PK-chunking to partition the query.
