Allow MariaDB Connector J to connect to Admin interface

Admin module should reply to this query:

SHOW VARIABLES WHERE Variable_name in
('max_allowed_packet','system_time_zone','time_zone','sql_mode');

See #204 (comment) for further details

A possible answer could be:

mysql> SHOW VARIABLES WHERE Variable_name in ('max_allowed_packet','system_time_zone','time_zone','sql_mode');
+--------------------+--------------------------------------------+
| Variable_name      | Value                                      |
+--------------------+--------------------------------------------+
| max_allowed_packet | 4194304                                    |
| sql_mode           | STRICT_TRANS_TABLES,NO_ENGINE_SUBSTITUTION |
| system_time_zone   | UTC                                        |
| time_zone          | SYSTEM                                     |
