func DecideOperation

func DecideOperation(serviceMaintenanceInfoVersion *version.Version, details paramparser.UpdateDetails) (Operation, error)

DecideOperation works out whether the platform (typically CloudFoundry) is trying to perform an Update of plan/parameters, or an Upgrade of Maintenance Info version. Is it an error to perform both at the same time. CloudFoundry provides only the fields it intends to change in the request body, but provides previous values for all fields. Where there is ambiguity, we rely on this CloudFoundry behavior.
