linkerd/linkerd2#2349 removed the `--single-namespace` flag, in favor of
runtime detection of cluster vs. namespace access, and also
ServiceProfile availability. This maintained control-plane support for
running in these two states.
This change requires control-plane components have cluster-wide
Kubernetes API access and ServiceProfile availability, and will error
out if not. Once #2349 merges, stage 1 install will be a requirement for
a successful stage 2 install.

The control-plane components relied on a `--single-namespace` param,
passed from `linkerd install` into each individual component, to
determine which namespaces they were authorized to access, and whether
to support ServiceProfiles. This command-line flag was redundant given
the authorization rules encoded in the parent `linkerd install` output,
via [Cluster]Role[Binding]s.
Modify the control-plane components to query Kubernetes at startup to
determine which namespaces they are authorized to access, and whether
ServiceProfile support is available. This allows removal of the
`--single-namespace` flag on the components.
Also update `bin/test-cleanup` to cleanup the ServiceProfile CRD.

`golangci-lint` performs numerous checks on Go code, including golint,
ineffassign, govet, and gofmt.
This change modifies `bin/lint` to use `golangci-lint`, and replaces
usage of golint and govet.
Also perform a one-time gofmt cleanup:
- `gofmt -s -w controller/`
- `gofmt -s -w pkg/`

When looking up service profiles, Linkerd always looks for the service profile objects in the Linkerd control namespace. This is limiting because service owners who wish to create service profiles may not have write access to the Linkerd control namespace.
Instead, we have the control plane look for the service profile in both the client namespace (as read from the proxy's `proxy_id` field from the GetProfiles request and from the service's namespace. If a service profile exists in both namespaces, the client namespace takes priority. In this way, clients may override the behavior dictated by the service.

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
