title: Azure Pipeline with Review Apps - Cleanup after merge
body: <p>I've been setting up a pipeline for our project with Azure Pipeline using yaml. Currently adding review apps with Azure Kubernetes Service and was wondering how we should clean up after the PR is merged.</p>
  
  <p>We are building docker images, pushing them to our registry, deploying them to a new dev space. Then it's all just left there.</p>
  
  <p>After merge we're never going to bed those images again, not like we're going to deploy from a unapproved PR and there's dozens of them every day. We also would like to delete the review app and take down those extra deployments after we're done with them </p>
  
  <p>I can't find anything in the documentation for this. Am I missing something?</p>
