> In most test cases, we start single broker so as to save resources. However,
> it could causes error when creating internal topics since they require 3
> replicas by default. In order to reducing the duplicate configs from all
> tests, we can add a bit sugar to auto adjust the replica factor (if it is not
> defined by tests) when the number of brokers started by tests is less then
> default value.
