Deltalinks provide chnage notifications.
Responses to an entityset that requests a deltalink by providing a $deltatoken=nnn are serialized using EdmDeltaSerializer, created with odata.creatEdmDelatSerializer().
The deltatoken can be read using uriinfo.getdeltaTokenOption()
$deltatoken is only applicable to certain requests, not including entity requets, but can include entityset with filters.
A POST/PUT/PATCH request can include in the HTTP Prefer Header "odata.track-changes" (example: request.addHeader("Prefer", "odata.track-changes"))
When received the response should include a deltalink that contains the deltatoken to access subsequent changes.
