    Find the ``zmq.Context`` from ``args`` and ``kwargs`` at call time.
    First, if there is an keyword argument named ``context`` and it is a
    ``zmq.Context`` instance , we will take it.
    Second, we check all the ``args``, take the first ``zmq.Context``
    instance.
    Finally, we will provide default Context -- ``zmq.Context.instance``
