AdminClient CreateTopics bug

[2021-08-02 06:53:48,396] INFO [Admin Manager on Broker 1001]: Error processing create topic request CreatableTopic(name='testt', numPartitions=1, replicationFactor=1, assignments=[CreatableReplicaAssignment(partitionIndex=0, brokerIds=[1001, 1002]), CreatableReplicaAssignment(partitionIndex=1, brokerIds=[1002, 1003])], configs=[]) (kafka.server.AdminManager)
org.apache.kafka.common.errors.InvalidRequestException: Both numPartitions or replicationFactor and replicasAssignments were set. Both cannot be used at the same time.

kafkajs.admin sends default numPartitions and replicationFactor so when I send replicaassignment only but send default values together

Fixed by #1305. KafkaJS now sends the default values -1 for replicationFactor and numPartitions, which is what's expected if you either want to use the default values from the cluster config, or if you are doing manual replica assignment. I have verified this in #1426.
