KIP-32 — Add timestamps to Kafka message

Accepted Kafka 1.0 BrokerProtocol

Adds a per-message timestamp field to the Kafka message format (both CreateTime and LogAppendTime modes), enabling log retention and rolling to be driven by message timestamps rather than file modification times. File modification time was unreliable after replica reassignment (timestamps reset to current time) and insufficient for streaming processing use cases that require event-time semantics.
