ClassNotFoundException for Kafka StatefulSet #40

We have a test environment on GKE v1.7.8. Kafka server pods keep failing with exception:

org.apache.kafka.common.KafkaException: com.linkedin.kafka.cruisecontrol.metricsreporter.CruiseControlMetricsReporter ClassNotFoundException exception occurred

This also leads to the crash of cruise-control and kafka-offset deployments.
