People working on this task will probably want to add a GET route to modules/openstack/files/puppet/master/encapi/ in operations/puppet.git (to make it quick to get data about all instances and their puppet classes in one query), and it will be exposed within the labs network at where a cumin backend can pick it up without needing to send hundreds of requests
