Support apoc.dump.jdbc

[johnlinp]

Feature description (Mandatory)

I would like to dump data from Neo4j database into other relational databases, e.g. PostgreSQL.
Just like apoc.load.jdbc, I would like to see a apoc.dump.jdbc.

Considered alternatives

I need to use a Spark application to load the data from Neo4j database and write into the relational database.

How this feature can improve the project?

It can increase the interoperability between Neo4j database and other databases.
