    Avoid UnhashableKeyWarning in api.nova.novaclient
    
    In python3, novaclient APIVersion instance is not hashable.
    If APIVersion insstance is passed to novaclient(),
    UnhashableKeyWarning will be emitted.
    An error message on UnhashableKeyWarning is emitted repeatedly
    and this can pollute error log with unuseful messages.
    
    To convert all unhashable arguments into hashable variables,
    a new decorator memoized_with_argconv is introduced.
    This decorator takes a converter function.
