ui: Ensure proxy instance health is taken into account in Service Instance Listings (#12279) 

We noticed that the Service Instance listing on both Node and Service views where not taking into account proxy instance health. This fixes that up so that the small health check information in each Service Instance row includes the proxy instances health checks when displaying Service Instance health (afterall if the proxy instance is unhealthy then so is the service instance that it should be proxying)

* Refactor Consul::InstanceChecks with docs

* Add to-hash helper, which will return an object keyed by a prop

* Stop using/relying on ember-data type things, just use a hash lookup

* For the moment add an equivalent "just give me proxies" model prop

* Start stitching things together, this one requires an extra HTTP request

..previously we weren't even requesting proxies instances here

* Finish up the stitching

* Document Consul::ServiceInstance::List while I'm here

* Fix up navigation mocks Name > Service

# Consul::ServiceInstance::List
A presentational component to show a list of Service Instances. The component
will display slightly different information based on whether you want the list
in a `@node` view or not.
Please note: A nice refactor here would be to let the node information be
added from the outside via a slot. Once component is using the new row based
scrollpane this can probably be looked at.
```hbs preview-template
<figure>
<figcaption>With no node given (i.e. from within a Service)</figcaption>
<DataSource
@src={{uri '/${partition}/${nspace}/${dc}/service-instances/for-service/${name}'
(hash
partition=''
nspace=''
dc='dc-1'
name='service-name'
)
}}
@onchange={{action (mut this.items) value="data"}}
/>
<Consul::ServiceInstance::List
@routeName="dc.services.show"
@items={{this.items}}
@proxies={{array}}
/>
</figure>
```
Component configured to show a list from within a node page.
```hbs preview-template

## Arguments

| `routeName` | `String` | | An Ember routeName for where clicking a row takes you |
| `node` | `(Object | boolean)` | | Whether to show a node like view |
