[hibernate-dev] [OGM] Neo4j integration dependencies

I would prefer to see these modules split as 3 different Maven
modules, but I wouldn't personally consider such work a priority.
Splitting them up would make for "lighter" fragments for e.g. Swarm,
but at the cost of a couple more paragraphs of documentation which
needs to be understood (more complex).
So I dislike the 2-modules tradeoff as users would be faced with the
additional configuration complexity, yet they would only get a
half-baked reward in exchange for it.
If you find some "interesting" Maven plugin which allows some kind of
build-time reorganization of these dependencies then please make sure
that we actually test the consumption of the output maven definitions.
In other words, I'd avoid that!
