Notifications options

The notifications feature in the Message service can be enabled by adding zaqar.notification.notifier stage to the message storage layer pipeline. To do it, ensure that zaqar.notification.notifier is added to message_pipeline option in the [storage] section of zaqar.conf:

[storage]
message_pipeline = zaqar.notification.notifier

For more information about storage layer pipelines, see zaqar-storage-drivers.
