This PR adds a test case for follower fetch when segments are archived and expired from remote storage. This test case verifies the following scenario (from [comment](https://github.com/apache/kafka/pull/11390/files#r1042140948)): 1. Leader is archiving to tiered storage and has a follower. 2. Follower has caught up to offset X (exclusive). 3. While follower is offline, leader moves X to tiered storage and expires data locally till Y, such that, `Y = leaderLocalLogStartOffset` and `leaderLocalLogStartOffset > X`. Meanwhile, X has been expired from tiered storage as well. Hence, `X < globalLogStartOffset`. 4. Follower comes online and tries to fetch X from leader. ### Committer Checklist (excluded from commit message) - [x] Verify design and implementation - [ ] Verify test coverage and CI build status -- This is an automated message from the Apache Git Service.
