CONFLICTS:
If reading from tiered storage is disabled, we would previously return an offset -1 if the epoch queried fell below the start of our local log.
This doesn't match what happens in Kafka, which returns the next available offset in a higher epoch. This behavior is matched by our lookup when reading from cloud storage.
This patch updates the Kafka handler to return the start offset of our local log if the requested term falls below the local log's beginning.
