Preview deleting an organization

Reports what deleting the organization would remove, without deleting it: members, whose memberships end (the first 100 and the total); assignments_removed, every assignment in its tree; nodes_deleted, beneath it; roles, its own roles; invites, the pending invitations revoked, by email; domains, its verified domains; sso_bindings and sso_connections, the connections bound to it and owned by it, by name; machine_clients, by name; and directory, whether its directory connection goes. The same sets the delete removes. People are named only for a reader who may see the Environment's people (people_named: env_identities.view in the Console, and production_identities.access in a production Environment; identity.view for an API key; access administration at the node for a tenant's administrator); anyone else gets the counts and empty lists. Read-only. Send version as If-Match on the delete. Requires the hierarchy.manage permission at the organization. Returns 404 when the id does not name a live organization in this Environment.
