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.
Create a ephemeral, in-memory TLS certificate authority and integrate it into the certificate distributor.
Remove the re-creation of deleted ConfigMaps; this will be added back later in #1248.

* Add TLS support to `conduit inject`.
Add the settings needed to enable TLs when `--tls=optional` is passed on the
commend line. Later the requirement to add `--tls` will be removed.

* Send controller namespace as separate field

* Add CA certificate bundle distributor to conduit install
* Update ca-distributor to use shared informers
* Only install CA distributor when --enable-tls flag is set
* Only copy CA bundle into namespaces where inject pods have the same controller
* Update API config to only watch pods and configmaps
* Address review feedback

The Destination service does not provide ReplicaSet information to the
proxy.
The `pod-template-hash` label approximates selecting over all pods in a
ReplicaSet or ReplicationController. Modify the Destination service to
provide this label to the proxy.
Relates to #508 and #741

The inject code detects the object it is being injected into, and writes
self-identifying information into the CONDUIT_PROMETHEUS_LABELS
environment variable, so that conduit-proxy may read this information
and report it to Prometheus at collection time.
This change puts the self-identifying information directly into
Kubernetes labels, which Prometheus already collects, removing the need
for conduit-proxy to be aware of this information. The resulting label
in Prometheus is recorded in the form `k8s_deployment`.

The conduit.io/* k8s labels and annotations we're redundant in some
cases, and not flexible enough in others.
This change modifies the labels in the following ways:
`conduit.io/plane: control` => `conduit.io/controller-component: web`
`conduit.io/controller: conduit` => `conduit.io/controller-ns: conduit`
`conduit.io/plane: data` => (remove, redundant with `conduit.io/controller-ns`)
It also centralizes all k8s labels and annotations into
pkg/k8s/labels.go, and adds tests for the install command.
Part of #201
