When replication of transactional control batch fails group coordinator steps down and return an error to transaction coordinator. Fixed the incorrect mapping of replication errors which may lead to returning an `unknown_server_error` to client. With the new mapping policy the error handling in consistent for all the replication batches. All the errors are translated to `not_coordinator_error`. The errors indicating uncertain outcome like shutting down and timeout are translated to timeout to let the client know that the outcome of operation must be verified.
