Review Comment:
You are right. It does load the end of metadata log. However,
BrokerMetadataPublisher calls initializeManagers before
dynamicConfigPublisher.onMetadataUpdate(delta, newImage), so the LogManager
cannot see either the latest broker-level configs or the latest cluster-level
configs if those dynamic configs are from the tail of the metadata log.
