type.yaml.tmpl: Add out-of-sync parameters

Add parameters that are presents on the puppet-openstack-cloud module
but not in the openstack-yaml-infra git repository.
I think this one is not explicit enough, could we rename it to lb_rabbit for example? (or something else)
Because I don't want someone thinking we disable RabbitMQ :-)
If you do that, you have to update the "type" file too.
