KIP-29 — Add an IsrPropagateIntervalMs configuration to KafkaConfig

Discussion Broker

Introduces an IsrPropagateIntervalMs broker config to batch and rate-limit ISR change notifications sent from brokers to the controller via ZooKeeper /isr_change_notification znodes. During broker bounces, a flood of concurrent ISR changes overwhelmed the controller with UpdateMetadataRequest storms, degrading the entire cluster.
