    oeqa/core/decorator/__init__.py: set metaclass to ABCMeta
    
    OETestFilter is a subclass of OETestDecorator. It wants to make
    use of @abstractmethod decorator. But such decorator requires
    metaclass to be ABCMeta to have effect. So add it now to achieve
    the designed behaviour.
    
    Comments from python's manual:
    """
    Using this decorator requires that the class's metaclass is ABCMeta
    or is derived from it.
    """
