to Range config validator. Ensure retention bytes cannot be 0
URL: https://github.com/apache/kafka/pull/5816
By adding a whitelist option to the `Range` config validator we can ensure
that certain configs can still use their special value of -1 while not being
less than a certain value

> Key: KAFKA-7517
> URL: https://issues.apache.org/jira/browse/KAFKA-7517
> Project: Kafka
> Issue Type: Improvement
> Reporter: Stanislav Kozlovski
> Assignee: Stanislav Kozlovski
> Priority: Minor
>
> Some configs like `log.retention.bytes` make no sense to have values of 0 -
> every log has a size of 0 upon creation and therefore every log should be
> deleted in this case.
> It would be useful to have some sort of guard, as limited as it could be, to
> help users not shoot themselves in the foot as easily (either by manual
> misconfiguration or some external tool (e.g k8s configmap
> ))
