Upgrade messages are now shown on the About screen rather than as alerts. Notifications that are marked as `top` or `custom` are still shown as alerts to allow for certain upgrade messages to be given more visibility.
- remove old `upgrade-notification` service
- update the `upgrade-status` service:
- add a `message` property that contains an upgrade notification if any exists
- add a `handleUpgradeNotification` method that accepts a Notification model instance and extracts the `notification.message` property into a html safe string for use in templates
- when loading server notifications during app boot, pass notifications that aren't marked as `top` or `custom` to the new `handleUpgradeNotification` method
- update the `about.hbs` template to pull the upgrade message from the `upgradeStatus` service
no issue
Automated tools, code generators, and editor integrations are increasingly standardising on the import style used in `ember-modules-codemod`. Our import style differed a little with regards to service/controller injection imports which meant we were starting to see inconsistent naming.
no issue
- add eslint-plugin-ember, configure no-old-shims rule
- run `eslint --fix` on `app`, `lib`, `mirage`, and `tests` to move imports to the new module imports
- further cleanup of Ember globals usage
- remove event-dispatcher initializer now that `canDispatchToEventManager` is deprecated

- adds custom `MaintenanceError` and associated error checking functions
- updates app route and notifications service to handle `503` errors via the `upgrade-status` service
refs https://github.com/TryGhost/Ghost/issues/6949
Handle version mismatch errors by:
- displaying an alert asking the user to copy any data and refresh
- disabling navigation so that unsaved data is not accidentally lost
Detailed changes:
- add `error` action to application route for global route-based error handling
- remove 404-handler mixin, move logic into app route error handler
- update `.catch` in validation-engine so that promises are rejected with the
original error objects
- add `VersionMismatchError` and `isVersionMismatchError` to ajax service
- add `upgrade-status` service
- has a method to trigger the alert and toggle the "upgrade required" mode
- is injected into all routes by default so that it can be checked before
transitioning
- add `Route` override
- updates the `willTransition` hook to check the `upgrade-status` service
and abort the transition if we're in "upgrade required" mode
- update notifications `showAPIError` method to handle version mismatch errors
- update any areas where we were catching ajax errors manually so that the
version mismatch error handling is obeyed
- fix redirect tests in editor acceptance test
- fix mirage's handling of 404s for unknown posts in get post requests
- adjust alert z-index to to appear above modal backgrounds
