- The only allowed route settings name is 'routes.yaml', which removes a need to parameterize the function as the location is permanent anyway
- Simplifying the function in any possible way before extracting the common bits into an external lib

- Frontend is not meant to know about the underlying source of the "routes" configuration, so any reads/edits/validations are being moved into a backend service. This should also simplify the coupling of the backend with the frontend where the latter will get a JSON blob with all needed configuration during the boot
- Nother problem the "get" method had was hiding an underlying function it was doing - reading the file from the filesystem SYNCRONOUSLY. It might be a thing we need to do during the "web" app initialization, but there's no clear need to do this in a sync fassion during the bootup for example. Also having a more explicit name should help :)
- The main goal here is getting this settings related code out of the routing service as it really doesn't belong there
- This settings file is used purely by the API to get and set files - its not really anything to do with actual routing
- This file calls out to the bridge to do a reload, which helps decouple slightly
- More refactoring is needed to get rid of the urlService dependency
- Note this file is really similar to the redirects one, it would be good to merge them
