Review comment:
This method does the validation part of `alterBrokerConfig` from
`ZkAdminManager` without persisting the configs in Zookeeper. This allows
validation of dynamic configs on brokers before they are forwarded to the
controller for both ZK and KRaft clusters.
The validation part of `alterBrokerConfig` is removed in this PR and
`alterBrokerConfig` now only persists the configs. This is done because the
request will only end up at the controller if the validation on the proxy
broker succeeded, and all that is left to do at that point is to persist the
configs.
