Description
This PR introduces native, secure support for using Cloud SQL as the PostgreSQL store backend for
ate-api-server.To ensure the highest level of security and ease of use in GCP environments, this integration leverages the Cloud SQL Auth Proxy sidecar with automatic IAM database authentication. This means transport security (TLS 1.3 tunnel) is handled automatically, and database sessions are authenticated using Workload Identity via short-lived OAuth tokens, completely eliminating the need for database passwords.
