KIP-1106 — Add duration based offset reset option for consumer clients

Accepted Kafka 4.0 ConsumerAdmin

Adds a duration-based offset reset option (`by-duration`) to consumer clients and the `kafka-consumer-groups.sh` tool, allowing consumers to reset to the offset corresponding to `now - duration` rather than only to earliest/latest/specific timestamp. With tiered storage enabling long retention, operators need a human-friendly way to seek back by time interval without computing an absolute timestamp.
