Review comment:
What do we do if the user is not a SCRAM user? Won't this throw an
exception? Can we make sure that user without quota or SCRAM credential doesn't
print any errors or exceptions?

Review comment:
I think we should also not allow users who authenticated using
delegation tokens to create or update users. We don't allow these users to
create new tokens, it would be odd if they could create a new user or the
password of the user of the token.

Does this need to be controller for Describe? It looks similar to
