It looks like the AutoTopicCreateManager
just wants to try to create the topics once without retry, which is fine to me because users can create the topic manually later. Left a comment. Thanks.

Don't you think this should be also an error we should log?

Log a warning for each topic that failed to be created as a result of an automatic creation. Previously, at the default log level, you could only see logs that the broker was attempting to autocreate topics. If the creation failed it was logged at debug. This makes it more visible.
