title: Why does pivotal cloud foundry does not remove a route when a corresponding app is deleted?
body: <p>I have been exploring Pivotal Cloud Foundry - Public Cloud Version by setting up an Pivotal Web Services account. 
  While exploring the CF CLI I followed the below tutorial.

  <p>I was able to successfully push the sample spring boot app to PCF Cloud and follow the tutorial.</p>
  
  <p>When I started to play around with it, I tried deleting the app using the below command. cf-spring is my app name.</p>
  
  <p>cf delete cf-spring

  <p>When navigated to my Pivotal Web Service account, I could see the app has been deleted. The route still displays the name of the route which was created when an app was created using the cf push command. </p>

  <p>So I tried to delete the route using the below command.

  <p>It does not allow me to delete using CLI ? Does the app delete command should have taken care to remove the related routes associated with the application ?</p>
