This PR begins to migrate Conduit to Linkerd2:
* The proxy has been completely removed from this repo, and is now located at
github.com/linkerd/linkerd2-proxy.
* A `Dockerfile-proxy` has been added to fetch the most-recently published proxy
binary from build.l5d.io.
* Proxy-specific protobuf bindings have been moved to
github.com/linkerd/linkerd2-proxy-api.
* All docker images now use the gcr.io/linkerd-io registry.
* `inject` now uses `LINKERD2_PROXY_` environment variables
* Go paths have been updated to reflect the new (future) repo location.
* Add controller admin servers and readiness probes
* Tweak readiness probes to be more sane
* Refactor based on review feedback

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 `stat` command did not support `service` as a resource type.
This change adds `service` support to the `stat` command. Specifically:
- as a destination resource on `--to` commands
- as a target resource on `--from` commands

* Add namespace as a resource type in public-api
The cli and public-api only supported deployments as a resource type.
This change adds support for namespace as a resource type in the cli and
public-api. This also change includes:
- cli statsummary now prints `-`'s when objects are not in the mesh
- cli statsummary prints `No resources found.` when applicable
- removed `out-` from cli statsummary flags, and analagous proto changes
- switched public-api to use native prometheus label types
- misc error handling and logging fixes

Conduit was relying on apps/v1 to Deployment and ReplicaSet APIs.
apps/v1 is not available on Kubernetes 1.8. This prevented the
public-api from starting.
Switch Conduit to use apps/v1beta2. Also increase the Kubernetes API
cache sync timeout from 10 to 60 seconds, as it was taking 11 seconds on
a test cluster.
Fixes#761

* Remove the telemetry service
The telemetry service is no longer needed, now that prometheus scrapes
metrics directly from proxies, and the public-api talks directly to
prometheus. In this branch I'm removing the service itself as well as
all of the telemetry protobuf, and updating the conduit install command
to no longer install the service. I'm also removing the old version of
the stat command, which required the telemetry service, and renaming the
statsummary command to stat.
* Fix time window tests
* Remove deprecated controller scrape config

Start implementing new conduit stat summary endpoint.
Changes the public-api to call prometheus directly instead of the
telemetry service. Wired through to `api/stat` on the web server,
as well as `conduit statsummary` on the CLI. Works for deployments only.
Current implementation just retrieves requests and mesh/total pod count
(so latency stats are always 0).
Uses API defined in #663
Example queries the stat endpoint will eventually satisfy in #627

When the conduit proxy is injected into the controller pod, we observe controller pod proxy stats show up as an "outbound" deployment for an unrelated upstream deployment. This may cause confusion when monitoring deployments in the service mesh.
This PR filters out this "misleading" stat in the public api whenever the dashboard requests metric information for a specific deployment.

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.
