Title: Allow not to specify params when getting route params

Not specifying will return all params, similar to how getPost, getQuery etc. in Http\Request.
This will allow to get all route params in a controller easily:
$this->params()->fromRoute();
instead of
$this->getEvent()->getRouteMatch()->getParams();
