Namespace selected via selector

[Allure996]

Please describe your use case / problem.
I set up a namespace-scoped traffic-manager, by inserting all the names of the namespace in which I wanted it to have permissions (same for clientsRbac)
This works fine, but if I will have more namespace I will update values.yaml everytime.

Describe the solution you'd like
Since the namespaces in my clusters have common labels, it would be nice to allow us to select namespaces using selectors.

Describe alternatives you've considered

Root Daemon    : v2.13.1
