    Use context.from_dict to determine available arguments

    RequestContext.__init__ takes and ignores arbitrary keyword arguments.
    This leads to mistakes such as those changed in tests and will prevent
    cinder from passing those keyword arguments to the base oslo_context
    class.

    The ignored arguments are generally made up of things that oslo_context
    added to the to_dict that cinder doesn't handle. Instead of accepting
    and ignoring those arguments make from_dict smart enough to construct
    the correct arguments to the class.
