[pbs-devel] [PATCH proxmox-backup 12/33] api-types: api: datatore: add notification-mode parameter

[Lukas Wagner]

This one lets the user choose between the old notification behavior
(selecting an email address/user and always/error/never behavior per
datastore) and the new one (emit notification events to the
notification system)
