List of notifications to be disabled.
Specify a list of notifications that should not be emitted.
A notification can be given either as a notification type to
disable a single event notification, or as a notification group
prefix to disable all event notifications within a group.
Possible values:
A comma-separated list of individual notification types or
notification groups to be disabled. Currently supported groups:
* image
* image.member
* task
* metadef_namespace
* metadef_object
* metadef_property
