    Document how to disable notifications
    
    This adds information to the "notification_format" config
    option help and notifications docs on how to disable notifications.
    
    While updating the config option help text, a stale reference
    to Pike is removed.

Title:
  impossible to disable notifications

Status in OpenStack Compute (nova) queens series:
  Confirmed

Bug description:
  Hi,

  As far as I can see from
  https://github.com/openstack/nova/blob/stable/queens/nova/rpc.py#L60-L86,
  it's currently (i.e. in queens) not possible to instruct nova to not
  send notifications - you either get versioned, legacy, or both.

  In clouds which don't have ceilometer, nothing is consuming the
  notifications, which keep piling up in rabbitmq :

  $ sudo rabbitmqctl list_queues -p openstack|grep -v 0$
  Listing queues ...
  notifications.error     32
  notifications.info      44908
  notifications_designate.info    15161
  versioned_notifications.error   24
  versioned_notifications.info    22285

  Could we please get a knob to make nova not send any notification ?

  Thanks !
