title: Changing the workspace name when using WireCloud with KeyStone
body: <p>After integrating KeyStone with WireCloud, the workspaces and the usernames look like the user name plus an id. Is there a way to configure KeyStone and/or WireCloud to only allow unique user names so that this id would not be neccessary?</p>
  
  <p>This seems only to happen, if a user name is already in use.</p>
