Feature Request

Is your feature request related to a problem? Please describe.

I want to configure a 301 Moved Permanently redirect for paths with a trailing slash, for example I want a request to /path/ to be redirected to /path, and apply this to all routes used by the app.

Describe the solution you'd like

Configuration option normalize_paths. If set to true, Loco should add corresponding redirects for me.

Describe alternatives you've considered

AFAIK in Axum there are two options:

1. Use RouterExt's route_with_tsr. It is not possible to use this trait when using Loco's Routes.
2. Use NormalizePath middleware to remove the trailing slash before routing. This requires wrapping the middleware around the entire Router, which is not directly exposed by Loco's Hooks before serving. The only way to accomplish that I see is to override serve with my own impl. Also this does not directly achieve what I want, because it will route both paths to the same handler instead of issuing a redirect.

Since Routes API is public, I can also iterate over handlers and create redirects manually myself, but this seems tedious and it would be really nice to have support for this from the framework.
