OGM-489 Neo4j parser

https://hibernate.atlassian.net/browse/OGM-489

I don't think we will be able to include this in the current release but at least I can have some feedback.

I forgot to add the cypher-dsl-dependency in the distribution package. I will add a commit for it.
I don't think we should be using the `org.fest.*` namespace. I'd move this to `org.hibernate.utils(.assertion)` and the test for the assertion to `org.hibernate.test(.assertion)`.
