   @MarvinCai Thanks for the help.
   I have one concern for non-partitioned topic creation:
   In command `partitioned topic create`, it will only create a node in zookeeper, and real topic creation is not included in that command; while `non-partitioned topic create` command will create the real one with managedLedger etc.
   So some times it is still useful to use `non-partitioned topic create` command to create topic, with name like "my-topic-name-partition-123".  I would suggest we check that 
   - the partition topic name "my-topic-name" already created in zookeeper;
   - partition number("123" in this example) is smaller than the partition number.
