    [CARBONDATA-308] [WIP] Use CarbonInputFormat in CarbonScanRDD compute

    Use CarbonInputFormat in CarbonScanRDD compute function
   
    1. In driver side, only getSplit is required, so only filter condition is required, no need to create full QueryModel object, so creation of QueryModel is moved from driver side to executor side.
    2. use CarbonInputFormat.createRecordReader in CarbonScanRDD.compute instead of use
    QueryExecutor directly

> Take CarbonScanRDD as the target RDD, modify as following:
> 1. In driver side, only getSplit is required, so only filter condition is required, no need to create full QueryModel object, so we can move creation of QueryModel from driver side to executor side.
> 2. use CarbonInputFormat.createRecordReader in CarbonScanRDD.compute instead of use QueryExecutor directly
