Use RabbitMQ default queue type for listener queues (#1878)

Remove explicit durable=False and set auto_delete=False to make
listener queues compatible with RabbitMQ's configured default queue
type. Previously, the queues were always created as classic queues
because durable=False and auto_delete=True are not supported by
quorum queues.

With these changes, the osism-listener-* queues will use the vhost's
default queue type (e.g., quorum queues in RabbitMQ 4 with the
openstack vhost created by migrate rabbitmq3to4 prepare).
