[PDI-12639] Hive/Hive2: Unable to pre-load connection to the connection pool.

Original hIve jdbc driver has a mess-up of the some methods implementations : 
- It always returns getAutoCommit() = true;
- it ignores setAutoCommit(false)
- it throw exception if setAutoCommit(true)

In fact it always works as usual driver with enabled autoCommit so invoke of the setAutoCommit method was overridden for ignoring behavior.
