* Opentracing needs to inject a span_context into data item which leaves the
* current execution context. Since device list updates are dumped in here
* and then processed later they need to include the span context for opentraing.
* Since we may also decide later to include other tracking information the column
* has just been called "context", the structure of the data within it may change.
