Summary of the changes (Less than 80 chars)

Fixes offset paging for Neo4j provider Updates documentation to note Cursor paging is currently not support (its not implemented)

Addresses a inconsistency in the test setup where a singleton Neo4jExecutable instance was created as part of the cached service provider. This lead to concurrent test execution inconsistencies.

@matt-psaltis Looks good :) just one question

[michaelstaib]

@matt-psaltis I have reworked the snapshot tooling ... so now the method is called Add, its just another extension method and handles all special cases. So if we find a query object on the result we will snapshot it together with the result. Can you rerun all neo4j tests and update the snapshots?

Did not want to do it in my change in order to avoid conflicts.

@matt-psaltis is there a reason paging got added to every single test?

[michaelstaib]

@arif-hanif you mean the order?
