[ENHANCE] Target multiple namespaces while requiring minimal rbac

Is your feature request related to a problem? Please describe. I cannot target multiple namespaces today without list and watch namespace rbac which i don't have.

Describe the solution you'd like Introduce a namespaces parameter that accepts a list of namespaces.

Describe alternatives you've considered The namespaceSelector cannot be used in this case because it requires unavailable permissions.
