Originally system would create compensation movements in case of difference on
frozen movements, but this is explicitely disabled.

The history of Hosting Subscription is fully written before alarm can chance to
run.

Forgot to remove the script.

The HostingSubscription_requestUpdateOpenSaleOrder is required (and tested).

Base is SlapOSCloud, run everything from there also on VIFIB.

Trigger Open Sale Order update in case of:
  * validated Hosting Subscription without validated OSO Line
  * archived Hosting Subscription without invalidated OSO Line

Trigger change on Person level by using scripts which are locking themselves,
so only one will run per Person.

As alarm is not critical for system operations run it only once by hour.

Drop user access for now.

erp5_open_trade provides open_sale_order_module.
