helk-kafka-base
+ updated Kafka to 2.0.0 (this affects Kafka brokers and zookeeper)
+ Created user kafkauser to run kafka containers as non-root

helk-kafka-broker
+ split entrypoint script to have topics creation separate
++ auomated the way how the container checks for the kafka broker port availability. If the port is open, then it attempts to create kafka topics

helk-zookeeper
+ updated entrypoint to only set the main server config
+ zookeeper is now started via Dockerfile CMD command
