 Review comment:
   @pnowojski I tried to extend from Kafka011ITCase : 
   public class Kafka10ITCase extends Kafka011ITCase
   but the prepare method : 
   public static void prepare() throws ClassNotFoundException {
       KafkaProducerTestBase.prepare();    //here
       ((KafkaTestEnvironmentImpl) kafkaServer).setProducerSemantic(FlinkKafkaProducer011.Semantic.AT_LEAST_ONCE);
   will trigger the method call chain : 
   protected static void startClusters(boolean secureMode, boolean hideKafkaBehindProxy) throws
ClassNotFoundException {
       // dynamically load the implementation for the test
       //here will load KafkaTestEnvironmentImpl from connector 0.11, not 1.0
       Class<?> clazz = Class.forName("org.apache.flink.streaming.connectors.kafka.KafkaTestEnvironmentImpl");
       kafkaServer = (KafkaTestEnvironment) InstantiationUtil.instantiate(clazz);
       LOG.info("Starting KafkaTestBase.prepare() for Kafka " + kafkaServer.getVersion());
   the `startClusters` is a static class, the `clazz` is the instance of KafkaTestEnvironmentImpl
from 0.11 module, and we can not use polymorphism to get a instance of KafkaTestEnvironmentImpl
from 1.0.
