Unpublish a plan
Unpublishing a plan makes a plan inactive. An unpublished plan cannot be assigned to a subscription.
Note: Existing subscribers will remain active on the plan. The plan
cannot be changed. If a subscriber changes plans they cannot return to the original plan. New
subscribers cannot be added to the plan.
Note: Unpublishing a plan does not unpublish the corresponding service.
