KIP-576 — Support dynamic update of more broker configs related to replication

Discussion BrokerAdmin

Extends Kafka's dynamic broker configuration (KIP-226) to cover additional replication-related settings including `fetch.max.bytes`, `replica.fetch.max.bytes`, `replica.fetch.backoff.ms`, `replica.lag.time.max.ms`, and others, enabling live tuning without broker restarts. These configs currently require a full broker restart to change, which is operationally disruptive during incidents involving replication lag or throttling.
