Support ZeroMQ in Cinder

Registered by Vivek Dhayaal

Right now, cinder supports only AMQP based messaging technologies like RabbitMQ or Qpid. Zeromq driver in oslo_messaging has been introduced for large-scale deployment. Cinder could take advantage of the Zer0MQ driver to scale out. So, introduce support for the ZeroMQ driver in Cinder.

http://zeromq.org/
ZeroMq is a very lightweight distributed messaging system specially designed for high throughput/low latency scenarios. Addition of support for ZeroMQ would help cinder scale out with high performance and be highly available as there is no centralised broker.

For the record:
Support for cinder ZeroMQ driver - tracked in bug #1440631
Support for multi-backend cinder ZeroMQ driver - TODO
DocImpact - YES
