Add / remove HTTP routes dynamically (better SNI support)

[ghost]

Passing nullptr to app.get(url, .. can be a way to unregister that route.

This can only be done for HTTP routes, WS routes cannot be removed

It's not just about adding/removing routes - it also needs to be per SNI.

You should attach routes to SNI domains, not the app itself.

App.sni("www.example.com").get("/someurl").post("/url").sni("www.another.com").get("/helllo").listen(3000).run()

To be backwards compatible it should default to "all" if you don't specify with sni what domain it is for.

There is now initial app.domain(server name).get(...).domain(another server name).get(...) support added.

Technically this is possible now - you can add and remove Server names, which removes all URL routes. So it is possible to remove-all-then-add-some to achieve removal
