The `conduit tap` command is now deprecated.
Replace `conduit tap` with `connduit tapByResource`. Rename tapByResource
to tap. The underlying protobuf for tap remains, the tap gRPC endpoint now
returns Unimplemented.

public-api and and tap were both using their own implementations of
the Kubernetes Informer/Lister APIs.
This change factors out all Informer/Lister usage into the Lister
module. This also introduces a new `Lister.GetObjects` method.

The TapByResource endpoint was previously a stub.
Implement end-to-end tapByResource functionality, with support for
specifying any kubernetes resource(s) as target and destination.

This changes the public api to have a new rpc type, `TapByResource`.
This api supersedes the Tap api. `TapByResource` is richer, more closely
reflecting the proxy's capabilities.
The proxy's Tap api is extended to select over destination labels,
corresponding with those returned by the Destination api.
Now both `Tap` and `TapByResource`'s responses may include destination
labels.
This change avoids breaking backwards compatibility by:
* introducing the new `TapByResource` rpc type, opting not to change Tap
* extending the proxy's Match type with a new, optional, `destination_label` field.
* `TapEvent` is extended with a new, optional, `destination_meta`.
* Extracted logic from destination server
* Make tests follow style used elsewhere in the code
* Extract single interface for resolvers
* Add tests for k8s and ipv4 resolvers
* Fix small usability issues
* Update dep
* Act on feedback
* Add pod-based metric_labels to destinations response
* Add documentation on running control plane to BUILD.md

When attempting to tap N pods when N is greater than the target rps, a rounding error occurs that requests 0 rps from each pod and no tap data is returned.
Ensure that tap requests at least 1 rps from each target pod.
Tested in Kubernetes on docker-for-desktop with a 15 replica deployment and a maxRps of 10.

Previously, running `$conduit tap` would return a `Unexpected EOF` error when the server wasn't available. This was due to a few problems with the way we were handling errors all the way down the tap server. This change fixes that and cleans some of the protobuf-over-HTTP code.

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.
