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 `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.

* 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.

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.

Stop ignoring the most significant labels of Destination names
Previously the destinations service was ignoring all the labels in a
destination name after the first two labels. Thus, for example,
"name.ns.another.domain.example.com" would be
considered the same as "name.ns.svc.cluster.local". This was very
wrong.
Match destination names taking into consideration every label in the
destination name.
Provisions have been made for the case where the controller and the
proxies with the zone name to use. However, currently neither the
controller nor the proxies are actually configured with the zone, so
the implementation was made to work in the current configuration too,
as long as fully-qualified names are not used.
A negative consequence of this change is that a name like
"name.ns.svc.cluster.local" won't resolve in the current configuration,
because the controller doesn't know the zone is "cluster.local"
Unit tests are included for the new mapping rules.

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.
