Proposal
Make universal OpenRTB and ID module that BidAdapters and ID providers can "inherit"

Make a universal OpenRTB 2.5 bidding module, that minimizes what bidder adapter has to do.... adapter would only define:
-httpEndpoint for bidding,
-httpEndpoint for cookieSyncs
-gvlID
-supported mediatypes (banner, native, video, audio)
-supported browser countries (most smaller bidders are teritory specific) (that would required geoIp module - can be serverside via JSON call)

If most bidders move to this simplified adapter overhead of maintaining (and pull requests) for > adapters would be greatly minimized.

---

Same goes for ID providers... most providers are simple JSON calls to serverside

If provider just defines
-httpEndpoint for ID resolving
-euid domain
-cookie name
-TTL

while all rest code is "inherited" from universal general ID module.
Most providers could use this general ID module

@slimkrazy @adam-browning would you mind reviewing the second item? We think this would be an opportune time to consolidate, let us know your feedback and if we should expect it.

@josepowera this is a great idea but not a breaking change; it could be merged with any release.
