For IBP 2.7 onwards, fetch responses include diverging epoch and offset in fetch responses if `lastFetchedEpoch` is provided in the fetch request. This PR uses that information for truncation and avoids the additional OffsetForLeaderEpoch requests in followers when `lastFetchEpoch` is known. ### Committer Checklist (excluded from commit message) - [ ] Verify design and implementation - [ ] Verify test coverage and CI build status - [ ] Verify documentation (including upgrade notes) ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
