> The handling of {{Offer::Operation::DESTROY}} in {{Try<Resources> Resources::apply(const Offer::Operation& operation) const;}} simply does a subtraction of the volumes from the resources. For regular persistent volumes this should suffice but for shared persistent volumes if there are multiple copies of the same shared volume in the resources object, the subtraction can't remove the volume, it simply removes a copy.
> This being a {{DESTROY}} operation means we do want to completely remove it and if we can't, the {{apply}} method should fail.
