I have analyzed the CI failures for PR #214.

• VirtualService v1 Error: The integration tests fail because the CI environment's Istio version is outdated and does not support networking.istio.io/v1. Since the goal of Upgrade VirtualService manifests from v1alpha3 to stable networking.istio.io/v1 #201 is specifically to move to stable APIs, this indicates the CI environment itself needs an upgrade.

• Etcd Error: The Profile Controller unit tests are failing due to a missing etcd binary in the runner's PATH, which is an existing infrastructure issue.

• 401 Unauthorized: There were GCS bucket access issues during the setup phase of several jobs.

All my manifest changes are strictly following the requested upgrade. Requesting a maintainer review.
