When integrating sort-connector-kafka-v1.15 and sort-connector-pulsar-v1.15, the unit test fails. I currently think it is a Maven dependency issue, which I will try to resolve later.

Thanks for your contribution.
Sorry, but If we don't use the open telemetry, why do we initialize it in the open method?
Maybe adding a new configuration to enable open telemetry is better?
