Flink support

Hi do we have a plan to support using this SDK in Flink? It seems that the CloudEvent class can not be serialized in Flink.

@slinkydeveloper Yeah that is what I want. I found that KafkaSerializerMessageWriterImpl will extract header attributes defined in CloudEvent and set them to the header variable. My final code looks like this

      override def serialize(element: CloudEvent, timestamp: lang.Long): ProducerRecord[Array[Byte], Array[Byte]] = {
        val headers = new RecordHeaders()
        val value = new CloudEventSerializer().serialize(topic, headers, element)
        new ProducerRecord(topic, 0, "string".getBytes(Charset.defaultCharset()), value, headers)
      }

Thank you very much for your help! 👍
