* Prometheus queries check results were being ignored
* Refactor verifyPromQueries() to also test when no prometheus queries
should be generated
* Add test for SkipStats=true
Includes adding ability to public.GenStatSummaryResponse to not generate
basicStats
* Fix previous test
We rework the routes command so that it can accept any Kubernetes resource, making it act much more similarly to the stat command.

This change alters the controller's Tap service to include route labels
when translating tap events, modifies the public API to include route
metadata in responses, and modifies the tap CLI command to include
rt_ labels in tap output (when -o wide is used).
Add a barebones ListServices endpoint, in support of autocomplete for services.
As we develop service profiles, this endpoint could probably be used to describe
more aspects of services (like, if there were some way to check whether a
service profile was enabled or not).
Accessible from the web UI via http://localhost:8084/api/services
Add a routes command which displays per-route stats for services that have service profiles defined.
This change has three parts:
* A new public-api RPC called `TopRoutes` which serves per-route stat data about a service
* An implementation of TopRoutes in the public-api service. This implementation reads per-route data from Prometheus. This is very similar to how the StatSummaries RPC and much of the code was able to be refactored and shared.
* A new CLI command called `routes` which displays the per-route data in a tabular or json format. This is very similar to the `stat` command and much of the code was able to be refactored and shared.
Note that as of the currently targeted proxy version, only outbound route stats are supported so the `--from` flag must be included in order to see data. This restriction will be lifted in an upcoming change once we add support for inbound route stats as well.

* Use ListPods always for data plane HC
* Missing changes in grpc_server.go
* Address review comments
* Read proxy version from spec

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 Reason to the error data passed from the api
- Rewrite error logic in the UI to try to make it clearer
- Show 0/0 pods meshed instead of 0/0 pods meshed (N/A) if 0 pods are meshed
- Return pod uptimes from the GetPods endpoint
- Adds filtering by namespace to api.GetPods
- Adds a --namespace filter to conduit get pods
- Adds pod uptimes to the controller component toolitps on the ServiceMesh page
- Moves the ServiceMesh page back to using /api/pods
Adds the ability to query by a new non-kubernetes resource type, "authorities",
in the StatSummary api.
This includes an extensive refactor of stat_summary.go to deal with non-kubernetes
resource types.
- Add documentation to Resource in the public api so we can use it for authority
- Handle non-k8s resource requests in the StatSummary endpoint
- Rewrite stat summary fetching and parsing to handle non-k8s resources
- keys stat summary metric handling by Resource instead of a generated string
- Adds authority to the CLI
- Adds /authorities to the Web UI
- Adds some more stat integration and unit tests
- It would be nice to display container errors in the UI. This PR gets the pod's container
statuses and returns them in the public api
- Also add a terminationMessagePolicy to conduit's inject so that we can capture the
proxy's error messages if it terminates
protobuf has a `go_package` option that can be used to explicitly name
Go packages such that they can be imported without additional rewrites.
This allows us to store proto files without additional, redundant
directories (which were used for packaging hints, previously).
This change adds an explicit `go_package` to all .proto files and
updates `bin/protoc-go.sh` to ensure these packages are output into
$GOPATH (so that the go_package can be absolute). This removes the need
to manually rewrite imports in bin/protoc-go.sh.
