requestMirrorPolicy property
Specifies the policy on how requests intended for the route's backends are shadowed to a separate mirrored backend service. Loadbalancer does not wait for responses from the shadow service. Prior to sending traffic to the shadow service, the host / authority header is suffixed with -shadow. Structure is documented below.
