The new StatSummary endpoint was only providing request volume and
successs rate information.
Add support for retrieving latency stats via StatSummary. Also make
all prometheus calls in parallel, and implement kubernetes test
fixtures.

The success rate calculation relies on the `classification` label, but
was incorrectly specifying `fail` rather than `failure`.
Fix public api to specify `failure`. Also re-org public api tests for
easier Kubernetes and Prometheus mocking.

The StatSummary logic was implemented as a method on http_server.
Move the StatSummary logic into grpc_server, for consistency with the
other endpoints.

The new statsummary command accepted friendly k8s names, which worked
for k8s queries, but Prometheus requires a specific key.
Modify the statsummary query to map friendly k8s names to canonical k8s
names when constructing the query. Then during the query, map the
canonical k8s name to a specific Prometheus label.

Start implementing new conduit stat summary endpoint.
Changes the public-api to call prometheus directly instead of the
telemetry service. Wired through to `api/stat` on the web server,
as well as `conduit statsummary` on the CLI. Works for deployments only.
Current implementation just retrieves requests and mesh/total pod count
(so latency stats are always 0).
Uses API defined in #663
Example queries the stat endpoint will eventually satisfy in #627
