Review comment:
Yes, I did think of that. I was not sure if to choose that path - less
transparent but easier to maintain. I suppose this can be kept at the level of
"advanced configuration" which needs code familiarity. I will make these
changes and push an update

> 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.
