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.
