[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
