title: Set App Service application setting from Azure DevOps yaml
body: <p>We are using AzureRmWebAppDeployment@4 for deploying our web app into an Azure App Service via a <code>yaml</code> file. So far, so good.</p>
  <p>Now we want to set few settings from yaml, rather than using a .json or .xml file</p>
  <p>Currently we do it manually through the Azure Portal -&gt; App Services -&gt; Configuration -&gt; Application Settings (see screenshot below)</p>
  <p>How we can do it programmatically from a yaml pipeline?</p>
