The existence of an invalid service profile causes `linkerd check` to fail. This means that it is not possible to open the Linkerd dashboard with the `linkerd dashboard` command. While service profile validation is useful, it should not lock users out.
Add the ability to designate health checks as warnings. A failed warning health check will display a warning output in `linkerd check` but will not affect the overall success of the command. Switch the service profile validation to be a warning.

If an input file is un-injectable, existing inject behavior is to simply
output a copy of the input.
Introduce a report, printed to stderr, that communicates the end state
of the inject command. Currently this includes checking for hostNetwork
and unsupported resources.
Malformed YAML documents will continue to cause no YAML output, and return
error code 1.
This change also modifies integration tests to handle stdout and stderr separately.
example outputs...
some pods injected, none with host networking:
```
hostNetwork: pods do not use host networking...............................[ok]
supported: at least one resource injected..................................[ok]
Summary: 4 of 8 YAML document(s) injected
deploy/emoji
deploy/voting
deploy/web
deploy/vote-bot
```
some pods injected, one host networking:
```
hostNetwork: pods do not use host networking...............................[warn] -- deploy/vote-bot uses "hostNetwork: true"
supported: at least one resource injected..................................[ok]
Summary: 3 of 8 YAML document(s) injected
deploy/emoji
deploy/voting
deploy/web
```
no pods injected:
```

supported: at least one resource injected..................................[warn] -- no supported objects found

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.
* Switch flag descriptions from lowercase to Capital

Kubernetes $KUBECONFIG environment variable is a list of paths to
configuration files, but conduit assumes that it is a single path.
Changes in this commit introduce a straightforward way to discover and
load config file(s).
Complete list of changes:
- Use k8s.io/client-go/tools/clientcmd to deal with kubernetes
configuration file
- rename k8s API and k8s proxy constructors to get rid of redundancy
- remove shell package as it is not needed anymore

The conduit dashboard command asychronously shells out and runs "kubectl
proxy".
This change replaces the shelling out with calls to kubernetes proxy
APIs. It also allows us to enable race detection in our go tests, as the
shell out code tests did not pass race detection.
