Currently, all "success"/"failure" classifications in the telemetry API are made based on the `grpc-status` trailer. If the trailer is not present, then a request is assumed to have failed. As we start proxying non-gRPC traffic, the controller needs to also be aware of HTTP status codes, so that non-gRPC requests are not assumed to always fail.
I've modified the telemetry API server to classify requests based on their HTTP status codes when the `grpc-status` trailer is not present.
I've also modified the `simulate-proxy` script to generate fake HTTP/2 traffic without the `grpc-status` trailer.

simulate-proxy sends HTTP example data.
Modify this test script to also send TCP example data.

Problem:
Simulate proxy would seemingly hang when used.
In simulate-proxy we were using rand.Uint32() to generate Count. This is way too big (in telemetry/server.go we call latencyStat.observe() Count times, so this loop was taking fovever).
Solution:
Use a count of 1 (as the surrounding loop will generate count requests)
Validation:
Script now works without hanging.
We’ve built Conduit from the ground up to be the fastest, lightest,
simplest, and most secure service mesh in the world. It features an
incredibly fast and safe data plane written in Rust, a simple yet
powerful control plane written in Go, and a design that’s focused on
performance, security, and usability. Most importantly, Conduit
incorporates the many lessons we’ve learned from over 18 months of
production service mesh experience with Linkerd.
This repository contains a few tightly-related components:
- `proxy` -- an HTTP/2 proxy written in Rust;
- `controller` -- a control plane written in Go with gRPC;
- `web` -- a UI written in React, served by Go.
