    Configure glance notification driver

    Glance does not use the message queue without the optional Telemetry
    service. Set default glance notification_driver values to noop. This
    prevents creation of a queue with no consumer and eliminates issues with
    the additional configuration necessary for notifications. The Telemetry
    chapter reconfigures glance to properly use notifications.
