* 1. Add the com.alibaba.otter.canal.connector.core.spi.CanalMsgConsumer file to the META-INF/canal directory under the pulsarmq-connector project
2. Introduce pulsar-client-admin for Canal to automatically create multi-partition topics
3. Add the judgment that roleToken is null
4. The disconnect method in CanalPulsarMQConsumer removes this.pulsarMQConsumer.unsubscribe();, this code will cause data loss during stop
5. When getting Pulsar messages, they are all processed as flat messages, because CanalMessageSerializerUtil.deserializer(data) will deserialize exceptions
6. Use groupId as subscriptName, without the pulsarmq.subscriptName parameter, the entire adapter will be the same subscriber name using pulsarmq.subscriptName
