Compatibility, Deprecation, and Migration Plan

ProducerConfig#addSerializerToConfig(Map<String, Object>...) is deprecated so as to remove it from public scope. A package-private replacement `appendSerializerToConfig` will be added and then used by KafkaProducer internally.

ConsumerConfig#addDeserializerToConfig(Map<String, Object>...) is deprecated so as to remove it from public scope. A package-private replacement `appendDeserializerToConfig` will be added and then used by KafkaConsumer internallyNo replacement, only deprecation.
