title: Automatically promote a nuget packge using a relese definition
body: <p>In onprem Azure DevOps (Version 17.143.28621.4) is there a way to automatically promote a nuget package from one view to another using a task in a release definition?</p>
  
  <p>When we trigger a release for a build, the artefacts (i.e. nuget packages) go through two stages</p>
  
  <ol>
  <li><strong>PreRelease</strong>: The packages are pushed to the feed (ending up in the @Local view).</li>
  <li><strong>Release</strong>: The packages should be promoted from the @Local to the @Release view.</li>
  </ol>
  
  <p>Unfortunately stage 2. is currently a manual step in the Azure DevOps web UI. Can it be automated via the release definition?</p>
  
  <p>If this is not possible, is there a better way to organise our release pipeline and package feeds/views to make a release of nuget packages fully automatic?</p>
