cubicweb #2574114 transform zmq uris from "tcp://" into something like "zmqpickle-tcp://" [done]

plain "tcp://" is confusing at the level of a cubicweb instance configuration

zmqpickle-tcp, zmqpickle-ipcs, zmqpickle-whatever may later be used more transparently

they also remember us that it is all based on the communication of pickles -- in some future we may want to use simpler communication means
