Since we likely want to use the ConfluentCommand support in the future, this uses kafka_sasl package instead of kafka_static. That allows us to continue using non-avro headers (which the kafka package uses), but still use ConfluentCommand. This also adds the Timeout logic to the kafka_sasl package.
