Support keepPreparedTxn=true on transaction coordinator. The ongoing transaction needs to be preserved (and its producerId / epoch needs to be preserved as well so that we can send transaction markers), but the client-facing producerId / epoch needs to move forward, so now we have 2 id / epoch pairs that need to be maintained during the Ongoing and Prepare states. To simplify state machine implementation, the transaction coordinator now eagerly rejects requests during the prepareCommit / prepareAbort states with CONCURRENT_TRANSACTIONS error - the client would get this error anyway and we avoid handing a complex combination of conditions that try to distinguish between retries and invalid requests. -- This is an automated message from the Apache Git Service.
