Restore the route_actual_response_total metric#468
Merged
Conversation
We export raw histograms for all HTTP metrics layers; but in some cases these values are never consumed. This change modifies the http metrics `Report` type to support disabling export of latencies. This feature is not used yet but will be used in a follow-up.
339efa8 incorrectly removed the route_actual metrics scope from the outbound stack. This change restores these metrics but omits latency buckets from export. Fixes linkerd/linkerd2#4215
