Make use of Kafka Key for Audit service and Kafka listener

* When message is sent by audit service, key will be the  CBA name
* When sent by kafka listener (self-service api), key is the same as the request message key consumed. If not specified, a random UUID
* MessageProducer interface refactoring :
  * add 'key' parameter to specify a key
  * add default value null to paramater 'headers' to remove some unnecessary method
