add mysql tls config

- Added a unique connection ID to the MySQL connection to improve TLS configuration management.
- The `Init()` function now registers the TLS configuration using the unique connection ID.
- Added error handling for TLS configuration registration.
- Modified `GetURL` to use the unique connection ID as the key for custom TLS configurations.
- This prevents issues with multiple connections potentially using the same TLS configuration.
