title: application gateway deployed using RM templates takes way too long
body: <p>I deploy a cluster with a simple application gateway using an RM template. The deployment stays for more than 30 minutes in deploying state with the appplication gateway being the bottleneck. It eventually succeeds. This is a very simple SSL gateway with a public IP.</p>
  
  <p>Any clues on what might be going wrong or how to troubleshoot something like this?</p>
