Migrate message queue configuration

Migrate from Magento 2.1 to 2.2

To upgrade the message queues from Magento 2.1, you must create the following files in the <module>/etc directory for each module that will use the message queue framework.

• queue_consumer.xml - Defines the relationship between an existing queue and its consumer.
• queue_topology.xml- Defines the message routing rules and declares queues and exchanges.
• queue_publisher.xml - Defines the exchange where a topic is published.

The existing queue.xml file is deprecated.

For complete details about these files, see Configure messque queues
