The clear_rabbit_queues script has been around forever, but it doesn't
appear to be widely used - e.g. there is no user documentation for it
and I don't see any mentions of it on mailing lists or Q&A forums.
Also, RabbitMQ now includes a management plugin and CLI which allows
you do do e.g.
$> rabbitmqadmin delete queue name=$topic
$> rabbitmqadmin delete queue name=$topic.$host
$> rabbitmqadmin delete exchange name=nova
oslo.messaging does not expose an API equivalent of this command since
even the existance of a queue is transport driver specific. We could
consider adding transport-specific admin CLIs, but probably not where
the transport already has suitable admin CLIs elsewhere.
For reference, this script was added by this merge:
