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.
* dest service: close open streams on shutdown
* Log instead of print in pkg packages
* Convert ServerClose to a receive-only channel

After this was implemented we found that ExternalName services are
represented in DNS as CNAMEs, which means that the proxy's DNS
fallback logic can be used instead of doing DNS in the control
plane. Besides simplifying the controller, this will also increase
fidelity with the proxied pods' DNS configuration (improve
transparency).
