-------------------------------------------

I'm sorry, I seem to have forgotten to create the Jira. I am almost done with 
this work. 
My WIP PR is 
https://github.com/apache/kafka/pull/13916/files#diff-70391f7b23b5528f11808d38481254c5e697e531e1d962f6f03bf759a2cca5fc


> Support delegation tokens in KRaft

> Delegation tokens have been created in KIP-48 and improved in KIP-373. KRaft 
> enabled the way to supporting them in KIP-900 by adding SCRAM support but 
> delegation tokens still don't support KRaft.
> There are multiple issues:
> - TokenManager still would try to create tokens in Zookeeper. Instead of this 
> we should forward admin requests to the controller that would store them in 
> the metadata similarly to SCRAM. We probably won't need new protocols just 
> enveloping similarly to other existing controller requests.
> - TokenManager should run on Controller nodes only (or in mixed mode).
> - Integration tests will need to be adapted as well and parameterize them 
> with Zookeeper/KRaft.
> - Documentation needs to be improved to factor in KRaft.
