When using oslo.messaging with RabbitMQ driver
On every start Heat creates 4 queues with the names like
b21828bd-80c3-4abf-8f50-0ffd71671d6b b21828bd-80c3-4abf-8f50-0ffd71671d6b.node-4 engine engine.node-4
two of them have contant names and other two have random names. So, the number of randomly named queues increases every time the Heat restarts
These queues has no "auto_delete" and "x-expire" options, so they will not be deleted until RabbitMQ cluster restarted
