CallbackNotFound errors found in API job logs

[Armando Migliaccio]

Example:

The API job configures the trunk plugin/OVS to be active. The OVS agent explicitly unsubscribe the callback [1] and thus we should avoid emitting noise. This is a sister change of [2]

Not RC2 worthy, as it's log noise more than anything else, but if we're in great shape, it's a one line change.

    Stop oslo_messaging from error logging CallbackNotFound

    This is expected when the server is pushing for a resource
    and some listeners (like the OVS agent) are not interested
    in the event. This happens when Trunk create/delete events
    are dispatched by the server.
