    [CARBONDATA-1271] Enhanced Performance  for Hive Integration with Carbondata

    There are various fixes added to improve the performance 
    - Added a DictionaryDecodeReadSupport class in Hive Package to directly convert to ArrayWritable
which is the default format for Hive
    - Removed the colids checks as it was hampering performance and causing issues with Map
jobs of Hive
    - Implemented getPos() method to return the rowCount
    - Made changes in core classes to support Hive Query Statistics
    - Improved and simplified CarbonHiveSerde
    - Support for Array Type and Struct Type added in the Integration 
    - Build passed with all test cases executing successfully for Spark 2.1 and Hadoop 2.7.2
    - Tested Manually for all the queries
