title: How to get all Spring profile names?
body: <p>I'd like to know if there's any programmatical way of getting <em>all</em> Spring profile names, active and inactive ?</p>
  
  <p>There are several questions where only the names of active profiles were needed. My question isn't answered by such questions as I also need the names of inactive profiles.</p>
  
  <p>Reason: I want to display all such profile names in a dropdown from which user can select which profile to use.</p>
