  Request versions summary:   
  - Version 1 is the same as version 0.
  - Version 2 adds the support for new error code PRODUCER_FENCED.
  - Version 3 enables flexible versions.
  - Version 4 adds VerifyOnly field to check if partitions are already in transaction and adds support to batch multiple transactions.
  Versions 3 and below will be exclusively used by clients and versions 4 and above will be used by brokers.

  Response versions summary:
  - Starting in version 1, on quota violation brokers send out responses before throttling.
  - Version 2 adds the support for new error code PRODUCER_FENCED.
  - Version 3 enables flexible versions.
  - Version 4 adds support to batch multiple transactions and a top level error code.
