Please move external libs to this folder only when you need external JDBC jars, for example:

ojdbc8-21.5.0.0.jar
orai18n-21.5.0.0.jar
mysql-connector-java-8.0.30.jar

Notes:

- MySQL, MariaDB, OceanBase, and TiDB SQL query metrics can use the built-in MySQL-compatible query engine without `mysql-connector-j`.
- If `mysql-connector-j` is present here, HertzBeat prefers JDBC after restart.
- Oracle and DB2 still require external JDBC jars in `ext-lib`.
