Future close(
{bool force: false}
)

Permanently stops this HttpServer from listening for new connections. This closes the Stream of HttpRequests with a done event. The returned future completes when the server is stopped. For a server started using bind or bindSecure this means that the port listened on no longer in use.

If force is true, active connections will be closed immediately.
