Describe the solution you'd like

I would like to be able to select namespace using globs so that I can apply company namespace naming convention.

Solution:

1. Add a feature switch such as clustersecretstore-allow-namespace-glob (boolean, default false)
2. Improve client_manager.go to support glob if feature is enabled

An example is the argocd AppProject , it is possible to use glob on destination namespaces

kind: AppProject
apiVersion: argoproj.io/v1alpha1
metadata:
  name: project-two
  namespace: argocd
spec:
 destinations:
  - namespace: 'team-two*'
    server: '*'

If you are interested in this feature I can contribute.

Describe alternatives you've considered

• Create one SecretStore per namespace
• Use Kyverno to mutate SecretStore ref
