    Avoid UnhashableKeyWarning in api.nova.extension_supported
    
    In python3, novaclient ListExtResource is not hashable.
    An error message on UnhashableKeyWarning is emitted repeatedly
    and this can pollute error log with unuseful messages.
    
    A tuple of extension names are now passed to the memoized
    decorator so that the decorator can hash it.
