Description

https://cwiki.apache.org/confluence/display/KAFKA/KIP-464%3A+Defaults+for+AdminClient%23createTopic

As of KIP-464, the adminclient can use '-1' as the replication factor or partitions and the broker defaults. The Kafka Connect Frame work does not currently accept anything less than 1 as a valid replication factor. This should be changed so that Connect worker configurations can specify `-1` for the internal topic replication factors to default to use the broker's default replication factor for new topics.
