[Hive] downgrade pom to Hive 0.13 to avoid the dependency snapshot mess from occurring

Hive 0.14 depends on (calcite) snapshot jars which have been deleted from their custom repo rendering Hive 0.14 unusable.
To avoid the issue from occurring downstream, downgrade to Hive 0.13.1 until 0.14.1 comes along.
The code is both binary and source compatible with Hive 0.13 and 0.14
