/**
* The `routes.yaml` file offers a way to configure your Ghost blog. It's currently a setting feature
* we have added. That's why the `routes.yaml` file is treated as a "setting" right now.
* If we want to add single permissions for this file (e.g. upload/download routes.yaml), we can add later.
*
* How does it work?
*
* - we first reset all url generators (each url generator belongs to one express router)
* - we don't destroy the resources, we only release them (this avoids reloading all resources from the db again)
* - then we reload the whole site app, which will reset all routers and re-create the url generators
