Envoy Proxy Health Discovery Service API

The Envoy Health Discovery Service (HDS) is a gRPC-based API that enables a management server to instruct Envoy to perform health checks on behalf of the control plane and report results back. This allows centralized health state management across a fleet of Envoy instances without requiring the control plane to perform health checks directly.
