title: Delete a Test Plan in VSTS / Test Manager
body: <p>Is there a way to delete a Test Plan in Visual Studio Team Services or through Microsoft Test Manager for a project hosted on Visual Studio Team Services?</p>
  
  <p>Delete buttons seems to be disabled and directly deleting the work item in VSTS is blocked:</p>
  
  <blockquote>
    <p>The work item 1 cannot be deleted. Test Plan work items cannot be deleted. work items cannot be deleted.</p>
  </blockquote>
  
  <p>Any other way to achieve this?</p>
