Implement the QuorumController side of KRaft metadata transactions. As specified in KIP-868, this PR creates a new metadata version, IBP_3_6_IV1, which contains the three new records: AbortTransactionRecord, BeginTransactionRecord, EndTransactionRecord. In order to make offset management unit-testable, this PR moves it out of QuorumController.java and into OffsetControlManager.java. The general approach here is to track the "last stable offset," which is calculated by looking at the latest committed offset and the in-progress transaction (if any). When a transaction is aborted, we revert back to this last stable offset. We also revert back to it when the controller is transitioning from active to inactive. In a follow-up PR, we will add support for the transaction records in MetadataLoader. We will also add support for automatically aborting pending transactions after a controller failover.
