We should build a simple app using the Oslo libraries that we can place in the oslo.messaging source tree to use for exercising the communication patterns of the library with different drivers. Ideally that would be a single app (or set of apps) that could be used to test all drivers, with

Hi, Working on zmq driver I've noticed that for now zmq.Context is created per socket which is definitely redundant. That was introduced by the change https://review.openstack.org/#/c/126914/5/oslo/messaging/_drivers/impl_zmq.py It makes the correct thing reducing the global context
