This new class is designed to be used in a ``GenericVNF`` object (VNF
or traffic generator) in a builder pattern. This consumer class will
be instantiated when initializing the ``GenericVNF`` derived object.
The ``GenericVNFConsumer`` endpoint is the ``GenericVNF``derived object
itself.
``GenericVNFEndpoint`` is an interface class to be inherited in a
``GenericVNF`` child object; the VNF object will implement the endpoints
methods.
NewVNF(GenericVNF, GenericVNFEndpoint):
def __init__(self, name, vnfd, task_id):
...
self._consumer = vnf_base.GenericVNFConsumer([task_id], self)
self._consumer.start_rpc_server()

Now "NSPerf" scenario will inform about the traffic generator PIDs after
setup process. With this information, IterationIPC runner will be able
to receive the messages sent by those traffic generators and control
the main iteration loop.
The following example, using vFW as VNF and OpenStack as context, makes
use of this new runner implementation:
/samples/vnf_samples/nsut/vfw/
tc_heat_rfc2544_ipv4_1rule_1flow_64B_trex_iterationipc.yaml

The messaging consumer now can store a list of PID of several producers.
The notification handler can compare the procedence of a message from
a list of PID.

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.
