* Refactor remaining `moduleFor`-tests
`moduleFor*` will be removed from ember-qunit v5
* Upgrade ember-qunit to v5
* Update how we use ember-sinon-qunit
With ember-qunit v5 we need to use ember-sinon-qunit differently.
* Fix submit-blank test
We can't click on disabled buttons with new test-helpers.
We need to adapt the test accordingly.
* Make sure we await fill-in with form yaml step
We need to await `fill-in`. This changes the reducer
function in the step to create a proper await
chain.
* Fix show-routing test
We need to await a tick before visiting again.
* Remove redundant `wait one tick`-step
* remove unneeded "next Tick" promise from form step
* Increase timeout show-routing feature
* Comment on pause hack for show-routing test
* Add some less fake API data
* Rename the models class so as to not be confused with JS Proxies
* Rearrange routlets slightly and add some initial outletFor tests
* Move away from a MeshChecks computed property and just use a helper
* Just use ServiceChecks for healthiness filtering for the moment
* Make TProxy cookie configurable
* Amend exposed paths and upstreams so they know about meta AND proxy
* Slight bit of TaggedAddresses refactor while I was checking for `meta` etc
* Document CONSUL_TPROXY_ENABLE
