Review Comment:
My understanding is that ApiVersions also contains features including
metadata version :)
I believe if the cluster supports this api, it will also support the api
versions that returns this. But might be a bit complicated
I wrote this before I saw the uuid check so maybe this is ok. I just wonder
if it will be slow to check all the topic IDs each time.
