> If bootstrap brokers does contain an unhealthy server, it can break the start
> of a whole Beam job. During the start, `KafkaUnboundedReader` is waiting for
> `setupInitialOffset()`. Wait timeout is either a double time of `request.
> timeout.ms` or some default constant. In both cases, it might not be enough
> time for kafka-client to initiate fallback and retry metadata discovery via
> another broker from given bootstrap list.
> The client should be able to specify timeout for `setupInitialOffset()`
> explicitly as a setting to KafkaIO read.
