Per-SNI routing, add/remove routes

[ghost]

If you have SNI, you can't really use the router since it is global for the app as a whole.

Maybe it could be possible to better integrate the SNI support with the router to allow dynamically adding/removing per-SNI routes? The SNI support already pretty much is a router by itself.

I will have a thinker about this, but it should definitely be possible to make more user friendly than currently.
