title: How to call Hapi Plugins for certain routes?
body: <p>Im using Hapi 12.1.</p>
  
  <p>Trying to figure out how to call certain extension points only on certain routes.</p>
  
  <p>For example for :
  '/hello' 
  I want to call three different extension points that work on the 'onRequest' step.</p>
  
  <p>For:
  '/goodbye'
  I want to call a different extension point that works also on the 'onRequest'  but is a different operation and a 'onPreAuth' step.</p>
  
  <p>For:
  '/health'
  Dont call any extension points, and just drop into the handler straight away..</p>
  
  <p>I have tried various ways to create a plugin, define the routes, and extension points. But it seems the the extension points are global, and dont only operation on the plugin's scoped routes.</p>
  
  <p>What am I missing?</p>
