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.
Fixes#804

The TapByResource command now has access to destination labels from the
proxy, but was not outputting them on the cli.
Modify the TapByResource output to print the destination pod label,
rather than the ip, when available.

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.

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`.
* CLI: change conduit namespace shorthand flag to -c
All of the conduit CLI subcommands accept a --conduit-namespace flag,
indicating the namespace where conduit is running. Some of the
subcommands also provide a --namespace flag, indicating the kubernetes
namespace where a user's application code is running. To prevent
confusion, I'm changing the shorthand flag for the conduit namespace to
-c, and using the -n shorthand when referring to user namespaces.
As part of this change I've also standardized the capitalization of all
of our command line flags, removed the -r shorthand for the install
--registry flag, and made the global --kubeconfig and --api-addr flags
apply to all subcommands.
* Switch flag descriptions from lowercase to Capital

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.

* Make Eos optional in TapEvent
grpc_status not being set in protobuf is the same as being set to zero,
which is also status OK
Modify TapEvent to include an optional EOS struct

* Add Eos to proto & proxy tap end-of-stream events
The proxy now outputs `Eos` instead of `grpc_status` in all end-of-stream tap events. The EOS value is set to `grpc_status_code` when the response ended with a `grpc_status` trailer, `http_reset_code` when the response ended with a reset, and no `Eos` when the response ended gracefully without a `grpc_status` trailer.
This PR updates the proxy. The proto and controller changes are in PR #204.
Part of #198. Closes#202

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.
