Test scenario

• Add logging part for Kafka and Zookeper in the examples/kafka/kafka-ephemeral.yaml file

  kafka:
      # ...
      logging:
        type: inline
        loggers:
         <logger.name>: "ERROR"
      # ...
  

  Logger names and more details can be found here: http://strimzi.io/docs/master/#assembly-logging-deployment-configuration-kafka

• Start Kafka cluster on ephemeral storage.
• Wait for deployment completion.
• Verify that proper logging level is using by checking logs for INFO, ERROR, WARN
