It isn't possible to pay on payzen zero amount invoices, so just update payment_mode to skip the payment from the search (to prevent bloat activities by relaunching activities that will never change the state of the object).

   Since an Support Request is updated by moving an Item to a project/organisation, its related Events should have their security updated too.

    This is required mostly to be able to edit parameters on the Hosting Subscription shared by others users.

    This feature, also allow us list "Project Members" in futures, to know it the invitations were used by proper users.

   Ensure that the user has proper Security once new assignments are created.

This option applies only the processing of partitions as in:
  `slapos node instance --force-stop`

This option affects how `started` partition are processed:
- buildout is processed normally
- the services are stopped instead of started
- no promises are run
- no report is sent to master

   Since the alarm was removed to auto-cancel, we now use an action to cancel users invoices.

    It is the only sign of debt the user could have.

   Follow up changes done on the original commited on erp5 repository. The goal of this test is run against the full stack of slapos master.

   If we limit the processing from this alarm the production execeeds the processing, and it never reaches the end.

   The list is filtered by the services that have base_amount with an invoicing (or subcategory of invoicing).

   There isn't a reason to check more often since the computer must be 30 days w/o contact master to be considered outdated.

   This isn't a decision to be taken automatically, but a decision for the site administrator

   This is mostly written by Kiril.
