Description

If a broker embeds a consumer and the broker itself doesn't start (e.g., conflicting broker id in ZK), the embedded consumer is still running. In this case, we should probably shut down the embedded consumer too.

To do this, we need to either throw an exception or return an error in KafkaServer.startup and act accordingly in KafkaServerStartable.startup.
