Review Comment:
Could we put the broker level validation in ControllerConfigurationValidator?

Review Comment:
Since all incrementalAlterConfigs requests are forwarded to the controller,
it's probably simpler to validate the request just in the controller. The logic
in preprocess() can just handle the logger config.

Review Comment:
It seems that we are duplicating the code from validateBrokerConfigChange().
Where is it needed?
