A new way to disable IAP accounts has been introduced recently.
This feature is mostly used in neutralization scripts to prevent
customers from accidentaly consuming their credits on their
staging/testing databases.
Documenting it will help users re-enable their accounts if they still
wish to use it in a testing environment.
