   Hi,
   - flink-1.10
   
   I found `FlinkKafkaProducer0xxx` unable to support  `KafkaSerializationSchema`, because of `FlinkKafkaProducer0xxx` need `KeyedSerializationSchema` or `SerializationSchema` as a serialization tool, I can't initialize like this.
   
   ```java
   public class ProducerSerializationSchema implements KafkaSerializationSchema<ConsumerRecord<byte[], byte[]>> {
       @Override
       public ProducerRecord<byte[], byte[]> serialize(ConsumerRecord<byte[], byte[]> element, @Nullable Long timestamp) {
           // do my logic
           return null;
       }
   }
   
   // flink streaming
   stream.addSink(new FlinkKafkaProducer011(
   	"default",
   	new ProducerSerializationSchema(),
   	properties,
   	FlinkKafkaProducer011.Semantic.EXACTLY_ONCE
   ));
   ```
