resolve router async

[katzIdo]

General description

a router is a sync function that retrieves endPoint from the registry.

if it doesn't find any endpoint then it returns null.

changing the router to be async will mean that normal routers will resolve immediately with null or endPoint.

but now, it will be possible to create routers that will be able to wait until the endPoint is available.
