provision: Use short name for assignee of ACE (BA, SA, CO, ...)

  Use short name (shortcut for wellknown SID/RID) for assignee in each entry of ACL (when possible)
  of sysvol files (GPO objects and netlogon folders).
  This avoid error prone substitution of DOMAINSID in ACL and make ACL clearer by using shortname
  for assignee accordingly with SDDL synthax rules. Translation to real SID is handled internaly by the
  from_sddl function.
