confluent cloud related values and dry run view command possibility

[mundey]

1. when we use confluent cloud cli (ccloud) to create topic, it does not require replication. the tool gives an error if not specifying replication in yaml
2. For customServiceAcls entry, host: is required in each while not sure if this is of any use for confluent cloud.
3. is it possible to see commands which will be executed in dry-run/plan mode or even when actual execution takes place, would be really useful to see how it's changing the cluster.
