> We use our own implementation of Kafka producer and consumer in our cloud environment for better integration with our infrastructure. The {{Consumer}} and {{Producer}} interfaces are properly implemented, but the implementation does not extend {{KafkaConsumer}} or {{KafkaProducer}}. Instead, it wraps and decorates the instance of the default Kafka implementation.
> I propose the following changes to make it easy to hook up our own implementation with Flink. 
>  * Refer to {{Consumer}} and {{Producer}} interface, not {{KafkaConsumer}} or {{KafkaProducer}} in {{FlinkKafkaInternalProducer}} and {{KafkaConsumerThread}}
>  * Add {{ConsumerBuilder}} and {{ProducerBuilder}} interface with the following definition
> {code:java}
> // ProducerBuilder
> Producer<K, V> build(Properties properties)
> // ConsumerBuilder
> Consumer<byte[], byte[]> build(Properties properties){code}
>  * Add new constructors in {{FlinkKafkaProducer}} and {{FlinkKafkaConsumer}} to pass in the {{ProducerBuilder}} and {{ConsumerBuilder}}.
