title: Angular 2 v3 router - how to get parent route parameters in child route
body: <p>I have a route defined as /abc/:id/xyz</p>
  
  <p>Where abc/:id resolves to a ComponentA and /xyz is a child component displayed in a router-outlet (ComponentB)</p>
  
  <p>When navigating to /abc/:id/xyz, when I do this.route.params.subscribe(...) (where route is an ActivatedRoute) in ComponentA i see the :id.  When doing the same thing in ComponentB I do not see :id.  I am guessing ActivatedRoute is using url segments.</p>
  
  <p>Is there anyway to get all the parameters in the route?</p>
