    Description:
Take CarbonDatasourceHadoopRelation as the target datasource definition, after that, CarbonContext can use standard Datasource strategy

In this Issue, change CarbonDatasourceHadoopRelation to use CarbonScanRDD in buildScan function.

  was:
Take CarbonDatasourceHadoopRelation as the target datasource definition, after that, CarbonContext can use standard Datasource strategy

In this Issue, following change is required:
1. Move the dictionary stratey out of CarbonTableScan, make a separate strategy for it.
2. CarbonDatasourceHadoopRelation should use CarbonScanRDD in buildScan function.
3. Change CarbonSource to use CarbonDatasourceHadoopRelation only, remove extension of BaseRelation, extend from HadoopFsRelation only.
