          Enumerate classes from class repository. If classname parameter
          exists, use it as the starting point for the hiearchy to get subclasses.
  
          Returns:
  
              return tuple including list of classes

              CIMError: CIM_ERR_INVALID_NAMESPACE: invalid namespace,

              of either the root or "ClassName" parameter was not found in the
              repository. This is probably a repository build error.
              CIMError: CIM_ERR_INVALID_CLASS: class defined by the classname
              parameter does not exist.
