Description

With KAFKA-8305, AdminClient allows to create topics based on the broker default replication factor.

Kafka Streams sets `replication.factor` to 1 by default atm, to give a good out-of-the-box user experience. The problem is, that people may need to change the config if they push an application to production.

We should change the default to `-1` to exploit the new AdminClient feature. This won't impact the out-of-the-box experience and may avoids the need to change the setting when pushing an application to production.
