Wikimedia has stopped using Ganglia (T177225)
The "labs" Cloud VPS project can be dismantled.
This means shutting down instances in the project, removing users/admins, cleaning up Hiera (via Horizon/Wikitech)
and as the final step to actually delete the project a cloud-admin has to run a script.
This should also remove the "Nova_resource:" links mentioned on T183873.
