KIP-570 — Add leader epoch in StopReplicaRequest

Accepted Kafka 2.6 ProtocolBroker

Adds a leader epoch field to `StopReplicaRequest` so brokers can fence out-of-order or stale stop-replica commands that arrive after a newer leader epoch has been established. Without an epoch check, a delayed `StopReplicaRequest` from a previous controller term could incorrectly stop a replica that is legitimately serving a newer leader, causing data unavailability.
