I agree that this is not something Climate should be in charge. If the
user wants to reserve a set of services and deploys them automatically,
Climate should provide the lease and Heat the deployment orchestration.
Also, for example, it may be good to be able to reserve automatically
the right amount of resources needed to deploy a Heat stack via Climate.
