This patch adds full traceback to ExceptionPayload in versioned
notifications.
The instance fault field and instance-action REST API has already
provide the traceback to the admin users (controlable through policy)
and the notifications are also admin only things as they are emitted
to the message bus by default. So it is assumed that security is not
a bigger concern for the notification than for the REST API.
On the ML [1] post there was no objection to add new string field to the
ExceptionPayload that will hold the serialized traceback object.
