I'm not sure why constructor of FieldIndexTopicSelector and
FieldNameTopicSelector are resurrected again, but I'm revoking +1 and now -1 on
this unless it removes specific meaning of "default".
As I said previously, there's no "default" topic in Kafka by default so it
should throw errors. We should force users to input default topic name to make
them prepared.
