Private k8s clusters, such as the private GKE clusters offered by Google
Cloud, cannot be reached through the current API proxy method.
This commit uses the port forwarding feature already developed.
Also modify dashboard command to not fall back to ephemeral port.

Add support for `linkerd check config`. Validates the existence of the
Linkerd Namespace, ClusterRoles, ClusterRoleBindings, ServiceAccounts,
and CustomResourceDefitions.

Currently, cli/cmd/root.go provides a couple of utilities for building
clients to Linkerd's Public API; however these utilities are infallible,
execute health checks, etc.
There are a class of API clients---for instance, when an inject command
wants to acquire configuration from the API---where these checks are
undesirable. The version CLI built such a client, for example.
This change consolidates the various utilities into a single file.
Furthermore, it renames these utilities to clarify they differ.
Consolidate timeouts for `linkerd check`
- Moved the creation of contexts from inside the methods targeted by the
checks into a single place in the runCheck() and runCheckRPC() methods
where the context is built using a hard-coded timeout of 30 seconds.
- k8s' client-go doesn't allow passing along contexts, but it let's us
setting the Timeout manually.
- Reworded the description for the --wait option.

Version checks were not validating that the cli version matched the
control plane or data plane versions.
Add checks via the `linkerd check` command to validate the cli is
running the same version as the control and data plane.
Also add types around `channel-version` string parsing and matching. A
consequence being that during development `version.Version` changes from
`undefined` to `dev-undefined`.

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.
* Remove package-scoped vars in cmd package
* Run gofmt on all cmd package files
* Re-add missing Args setting on check command

* 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.

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.
