Enable the resetNamespace option when generating routes

[marcioj]

Since emberjs/ember.js#11517 resource('some route') is deprecated in favor of route('some route', { resetNamespace: true }). This PR enables the resetNamespace option in routeGenerator#add. For instance:

routes.add('foos', { resetNamespace: true })

generates

Router.map(function() {
  this.route('foos', { resetNamespace: true });
});

The idea is to use this option later in the ember-cli route generator via --reset-namespace

Any update here?

@marcioj thanks :) I'll do a release in a bit, can you please upgrade ember-cli docs to document this stuff?

Sure :). I'll send a PR to ember-cli to include the --reset-namespace option and also add some information about it.
