title: Set Azure App Service environment variables with microsoft devops deploy task
body: <p>For years we stored our environment variables in devops pipelines (for each environment) and had a custom powershell script for updating them on deploy.</p>

  <p>recently on another project with similar need, I discovered that the task <code>Àzure App Service Deploy</code> had an <code>app settings</code> section, great. seems to be exactly what is needed to <strong>get rid</strong> of our powershell custom script.</p>
  
  <p>however I didn't found (official documentation of the task doesn't mention it) how to re-use pipeline variables into task <code>app settings</code>. any idea if it's possible ?</p>
