  Request versions summary:   

  Response versions summary:
  - Version 1 adds fields for the rack of each broker, the controller id, and
  whether or not the topic is internal.
  - Version 2 adds the cluster ID field.
  - Version 3 adds the throttle time.
  - Version 4 is the same as version 3.
  - Version 5 adds a per-partition offline_replicas field. This field specifies
  the list of replicas that are offline.
  - Starting in version 6, on quota violation, brokers send out responses before throttling.
  - Version 7 adds the leader epoch to the partition metadata.
  - Starting in version 8, brokers can send authorized operations for topic and cluster.
  - Version 9 is the first flexible version.
  - Version 10 adds topicId.
  - Version 11 deprecates ClusterAuthorizedOperations. This is now exposed
  by the DescribeCluster API (KIP-700).
  Version 12 supports topicId.
