this commit introduces a new submodule to `linkerd-http-prom`. this submodule includes a `NewRecordStatusCode<N>` middleware that records Prometheus metrics counting response status codes for HTTP and gRPC traffic. Signed-off-by: katelyn martin <kate@buoyant.io>
this is akin to #3334, which cleaned up the equivalent expression in `linkerd/app/outbound/src/http/logical/policy/route/metrics.rs`. Signed-off-by: katelyn martin <kate@buoyant.io>
before we introduce additional layers to our backend stack, we should define type aliases as prophylaxis against: <https://rust-lang.github.io/rust-clippy/stable/index.html#type_complexity> Signed-off-by: katelyn martin <kate@buoyant.io>
