kubectlRun to avoid conflating stdin and stdout in tests#15151Conversation
… tests Introduce a new test helper `TestHelper.KubectlRun` (and mark `TestHelper.Kubectl` as deprecated), that keeps stdout and stderr separate when invoking `kubectl`. This avoids failures on Kubernetes 1.35+, where deprecation warnings for Endpoints are emitted alongside command output and can break deserialization in `TestDestinationAPIStreamTracksRolloutEndpoints`.
