In order to test certain setups for our metrics visualizations we need to be able to setup several different `ui_config` settings during development/testing. Generally in the UI, we use the Web Inspector to set various cookie values to configure the UI how we need to see it whilst developing, so this PR:
1. Routes `ui_config` through a dev time only `CONSUL_UI_CONFIG` env variable so we can change it via cookies vars.
2. Adds `CONSUL_METRICS_PROXY_ENABLE`, `CONSUL_METRICS_PROVIDER` and `CONSUL_SERVICE_DASHBOARD_URL` so it's easy to set/unset these only values during development.
3. Adds an acceptance testing step so we can setup `ui_config` to whatever we want during testing.
4. Adds an async 'repository-like' method to the `UiConfig` Service so it feels like a repository - incase we ever need to get this via an HTTP API+blocking query.
5. Vaguely unrelated: we allow cookie values to be set via the location.hash whilst in development only e.g. `/ui/services#CONSUL_METRICS_PROXY_ENABLE=1` so we can link to different setups if we ever need to.
All values added here are empty/falsey by default, so in order to see how it was previously you'll need to set the appropriate cookies values, but you can now also easily preview/test the the metrics viz in different/disabled states (with differing `ui_config`)
* ui: ServiceInstance.Name should be the Service.Name, never the ID
The ServiceInstance.ID should try Service.ID and fallback to
Service.Name, not ServiceInstance.Name. ServiceInstance.Name is just an
alias to Service.Name which is always set.
* ui: Fixup service instance healthcheck list not to show ghost check
If the proxy is undefined, then an undefined vaule is appended to the
list of checks
* There are only 6 checks in the mocks so only expect 6
