[CARBONDATA-2950]alter add column of hive table from carbon for spark
versions above 2.1
### Problem:
spark does not support add columns in spark-2.1, but it is supported in 2.2
and above
when add column is fired for hive table in carbon session, for spark
-version above 2.1, it throws error as unsupported operation on hive table
### Solution:
when alter add columns for hive is fired for spark-2.2 and above, it should
not throw any exception and it should pass
