KAFKA-14499: [1/N] Introduce OffsetCommit API version 9 and add new S…
…taleMemberEpochException error (#14046) This patch does a few things: 1) It introduces version 9 of the OffsetCommit API. This new version has no schema changes but it can return a StaleMemberEpochException if the new consumer group protocol is used. Note the use of `"latestVersionUnstable": true` in the request schema. This means that this new version is not available yet unless activated. 2) It renames the `generationId` field in the request to `GenerationIdOrMemberEpoch`. This is backward compatible change. 3) It introduces the new StaleMemberEpochException error. 4) It does a minor refactoring in OffsetCommitRequest class.
