Ingress gateway, proxy defaults and envoy_public_listener_json

Overview of the Issue

consul ingress gateway envoy is not including envoy_public_listener_json filter. This is needed for example to specify access logs, to see why an ingress is sometimes gives a 5xx error or specify response headers for distributed tracing (response headers). Without this critical info, it becomes difficult to isolate whether problem is on the gateway side or upstreams. This issue is only with ingress gateway and normal services do show filters specified in envoy_public_listener_json

Thanks for the help!
