Jacky Li updated CARBONDATA-312:
--------------------------------
    Description: 
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
