title: Adding programmatically new route to zuul proxy
body: <p>I am using a spring boot application with <code>@EnableZuulProxy</code> annotation. But I would like to add custom routes during runtime. How is this possible? </p>
  
  <p>Existing documentation only shows static examples, in which routes are defined in the <code>application.yml</code>. Could you point me to code snippets of my use case.</p>
  
  <p>In the <code>ZuulConfiguration</code> I found a possibility to add routes <code>routeLocator().getRoutes().add(route);</code> but they are not applied to the runtime. What am I missing?</p>
  
  <p>Thanks a lot. Cheers</p>
