Add support for REDUCE

[GiancarloLelli]

Hi all I was trying to translate a Cypher statement that contained the REDUCE instruction, but the parse method fails saying that the REDUCE expression is not supported. Any change this get added?

The statement can be found here: https://neo4j.com/graphgist/movie-recommendations-with-k-nearest-neighbors-and-cosine-similarity

The need to conversion risen because I'm trying to implement that k-NN logic and cosine similarity on Azure Cosmos DB.
