    [zmq] Dynamic connections send failure

    For dynamic connections it is crucial to close connection
    and not to have hanging sockets either we have sent message
    successfully or not.

    eventlet.green.zmq by default blocks the calling thread on sending message
    when connection was not established yet (which is correct DEALER
    socket behavior though), but socket cannot be closed when we hang on
    sending forever (if we never get the valid host to connect).

    eventlet also shields EAGAIN exception in default (blocking) sending mode
    so we need to use async zmq.NOBLOCK flag to receive this exception
    and hanlde it in our own way to not block forever.
