This change implements SASL authentication in the Kafka chart. Kafka and Exporter credentials are defined in the endpoints section, while other credentials for producers and consumers can be defined in the jaas section. Additionally, a few server settings are provided to enable SASL auth, and a jvm_options key is introduced. Any options specified here will be set when starting Kafka, including the location of the jaas file in this case. Change-Id: I43469c5bb5734b62cf69be924fe9cf7078e82a9c
