Feature request: page view ID

[acsbendi]

Page view ID is a simple unique ID that's generated when Prebid.js loads on a web page. It is already sent by Prebid.js to Prebid-server. The next step would be to expose it to the Prebid-server adapters. I have a PR with the proposed implementation.

More details can be found in the original issue in Prebid.js.

Discussed with the PMC. Two main questions were raised:

1. Should page view ID be in bidderconfig or is it ok to keep it in $.ext?
   2a) Should we generate a page view ID for bidders defined server-side? One proposal is to allow a dedicated page view ID used specifically for this purpose to be passed to PBS which would then be used to derive a unique page view ID for each bidder.
   2b) If you're going to do this for page view, should we also do it for session? The session ID can be derived from the same ID received in the request. Note that a session here refers to activity on a particular domain.

Moving to community review and we will revisit at the next PMC.

@bsardo Thank you for the response!

1. I would consider bidderconfig to only contain data manually defined rather than generated programmatically by Prebid, that's why it is currently in $.ext. I also tried to follow the (apparent) convention based on ext.prebid.aliases.
   2a. Yes, that sounds like a good idea! Would it need its own field in the request from Prebid.js or is it fine to use a special identifier for it (e.g. PREBID_SERVER or just an empty string) and send it in the same ext.prebid.page_view_ids structure as the rest of the IDs?
   2b. I could try, but originally I was only planning to add support for page view ID. Would session IDs need to be generated in the same way as the page view IDs in Prebid.js. then sent in the request to Prebid server?

Any update or timeline on this, @bsardo?
