ui: Notifications re-organization/re-style (#11577)
- Moves where they appear up to the <App /> component.
- Instead of a <Notification /> wrapping component to move whatever you use for a notification up to where they need to appear (via ember-cli-flash), we now use a {{notification}} modifier now we have modifiers.
- Global notifications/flashes are no longer special styles of their own. You just use the {{notification}} modifier to hoist whatever component/element you want up to the top of the page. This means we can re-use our existing <Notice /> component for all our global UI notifications (this is the user visible change here)

# notification
Consul UIs notification modifier is used to 'hoist' DOM elements into the
global notification area for the UI. The most common usage will be something
like the below:
```hbs preview-template
<figure>
<figcaption>Attach a Warning notice to the top of the app ^^^</figcaption>
<Notice
class="notification-update"
@type="warning"
{{notification
sticky=true
}}
as |notice|>
<notice.Header>
<strong>Warning!</strong>
</notice.Header>
<notice.Body>
<p>
This service has been deregistered and no longer exists in the catalog.
</p>
</notice.Body>
</Notice>
</figure>
```
Currently this is backed by `ember-cli-flash` and the named options are
currently options that can be accepted by `ember-cli-flash`. Be aware that this
is likely to change in the future.
