placeableDatacenters
The datacenters this deployment can create an app in. Call this before createApp and use a returned code as input.datacenter: the argument is REQUIRED and permanent, because an app is distributed on its app_id and all of its data lives in one datacenter for the life of the app. Requires authentication. Offer only entries with placeable=true; an empty list means no datacenter topology has been pushed here and app creation will refuse until it has. Cheap and stable — the answer changes only when the fleet does, and it is served from Citus reference tables on whichever instance answers.
