title: Dialogflow API V2 "End of conversation" flag in webhook request
body: <p>I am migrating a Dialogflow agent to API V2, and I am having an issue related to the "Set this intent as end of conversation" option</p>
  
  <p><a href="https://i.stack.imgur.com/pJXqzm.png" rel="noreferrer"><img src="https://i.stack.imgur.com/pJXqzm.png" alt="enter image description here"></a></p>
  
  <p>My fulfillment webhook relies on the <code>"endConversation": true</code> property of the V1 webhook request's metadata to perform custom platform logic.</p>
  
  <p>Is there any way I can expose this same property in Dialogflow V2 without using a custom payload?</p>
