Add a rabbit_transient_queues_ttl and amqp_auto_delete params The amqp_auto_delete option needs this patch: https://review.opendev.org/c/openstack/puppet-oslo/+/944132 . Since transient_queues_ttl is also managed by oslo::messaging::rabbit, there's no way to use ceilometer_config to set it, so this patch is mandatory for one to set rabbit_transient_queues_ttl in ceilometer.conf.
