closes #11999
- When the routes.yaml file changes (manually or through API) we need
to store a checksum to be able to optimize routes reloads in the future
- Added mechanism to detect differences between stored and current routes.yaml hash value
- Added routes.yaml sync on server boot
- Added routes.yaml handling in controllers
- Added routes hash synchronization method in core settings. It lives in core settings
as it needs access to model layer. To avoid coupling with the frontend settings it accepts
a function which has to resolve to a routes hash
- Added note about settings validation side-effect. It mutates input!
- Added async check for currently loaded routes hash
- Extended frontend settings loader with async loader. The default behavior of the loader is
to load settings syncronously for reasons spelled in 0ac19dcf84
To avoid blocking the eventloop added async loading method
- Refactored frontend setting loader for reusability of settings file path
- Added integrity check test for routes.yaml file
