Add MQ consumer, producer and payload base classes
Added MessagingProducer base class. A class implementing this base class can send a cast message using the MQ service installed in the Yardstick jumphost (RabbitMQ by default, other MQ could be implemented). The producer will send messages to an specific topic. Added MessagingConsumer base class. A class implementing this base class will be able to receive any message sent by a MessagingPorducer class publishing messages in the topic subscribed. By default both Producer and Consumer "fanout" is True. That means every Consumer will create a fanout Queue attached to the MQ Exchange topic. All Consumers attached to this topic will receive the message sent by the Producer [1]. Added Payload base class. To send data through the message queue service, a Payload derived object should be created. This base class allows to define the attributes container in the class, convert the object to a dict and retrieve the object from a dict. Added a new library, "oslo.messaging", to implement the RPC client and server.
