Background and Approach (Required)

• Namespace management feature was contributed by https://github.com/argoproj-labs/argocd-operator/pull/1687 and https://issues.redhat.com/browse/GITOPS-6179
• However, we were unable to add E2E tests to that repo, because this feature requires modifying the operator subscription (which is not supported via argocd-operator E2E tests)
• We should thus contribute comprehensive E2E tests for this feature to gitops-operator Ginkgo tests
• Tests should cover all aspects of feature
• Some example tests:
  • Enable/disable namespace management and ensure that appropriate roles/bindings are added/removed from namespace
  • Ensure that glob filter matching is supported
  • Ensure that when the feature is disabled, or managedBy or modified, that roles/bindings are always cleaned up
  • Security tests:
    • Ensure that feature only works when namespace management env var is set
    • Ensure that if ArgoCD CR does not have managedby, that roles are NOT added
  • etc
