Descrizione

Title: Expose x-envoy-upstream-service-time as a metric

Description:

I want to be able to attribute latency to each portion of my network. Whilst I have tracing data which may enable me to do this, it would be much easier if I had access to the data from the X-Envoy-Upstream-Service-Time header available as a metric. I have not been able to determine a way to calculate this with the existing exposed metrics.
