Add support for KafkaAvroSerializer in apex-pdp
Adding the support for KafkaAvroSerializer to deserialize the messages sent on a kafka topic using the KafkaAvroSerializer. The default StringDeserializer that comes from KafkaConsumer is not able to work with avro encoded messages. Issue-ID: POLICY-4369 Change-Id: Ia97bee9546baa78c237e21a220df9374b84121dd Signed-off-by: Ram Krishna Verma <ram_krishna.verma@bell.ca>
