Is your proposal related to a problem?

Hi,
When new kafka consumer gives me a request to approach kafka ui (for readonly),
i have to rewrite rbac yaml file.
I deployed two Kafka UI to solve this problem.
First one has basic authentication is for admin users.
The other one is readonly for kafka consumers.

Describe the feature you're interested in

I think it is useful if the way i can setup default role is exists.

rbac:
  roles:
    - name: "admins"
      clusters:
        - development
      subjects:
         - provider: oauth_github
           type: user
           value: 'seono'
      permissions:
        ...
    - name: "readonly"
      clusters:
        - development
      subjects:
        - provider: oauth_github
          type: default
      permissions:
        ...

Describe alternatives you've considered

I know there is other type organization and team.
If someone wants readonly permission, I can invite them to the group.
But.. In my case, my company has too many organzations and teams so i can not use it properly.
