[CARBONDATA-3641] Refactory data loading for partition table
[Background]
Currently, CarbonData only implemented hadoop commit algorithm version 1, which generated too many segment files during loading and generated too many small data files and index files
[Modification]
1. implemented carbon commit algorithm, avoid to move data file and index files
2. generate the final segment file directly
3. optimize global_sort to avoid small files issue
4. support complex data type in partition table (non-partition column)
This closes #3535
