title: Azure Devops 2019 builds are not deleted by retention policy
body: <p>I have builds set up in Azure DevOps 2019 and my builds are generated using yml. I have so many builds that I do not need them so.
  I have setup my release retention policy to 30 days which works fine. How ever I am interested in deleting the old build and it doe snot have effect on them. Where and how can I setup the retention policy to delete builds. I could not find any place from the left hand navigation in the azure devops or on the build page.</p>
