Additional context

With the addition of inferred services, trace metrics from http clients will show up as part of the calling service. These metrics are used to show latency metrics to downstream services. Right now the errors that are shown only apply to 4xx errors. This is misleading as 5xx errors do not show in the UI as an error for downstream calls to other services.
