Imp task like managing the topic, consumer group and entity configuration.

Example - Application need to produce an event to the topic. First the topic need to exists. Before adminClient options are UNKNOWN_TOPIC_OR_PARTITION exception from the producer.send() and let user know that topic does not exist or Kafka cluster to enable automatic topic creation.
