Description

Since Kudu has a notion of primary keys, we need Postgres tables of migrated Impala/Kudu table to have the same. This Jira is about altering the migration support in data_generator.py to read source tables (DESCRIBE EXTENDED), detect whether they have primary keys kudu.key_columns, and create the postgres table with the same primary keys.
