    core: wait for connection addition to be ready
    
    Apparently we need to wait a bit before pluto is ready to talk to
    us, and if we don't, we get the error:
    
    "need --listen before --initiate"
    
    which means that pluto hasn't created the control socket that
    whack listens on yet.  "--ready" waits until that happens.
