Use WITH $param to pass nodes in Neo4j implementation

[szarnyasg]

Our current Neo4j transformations get the ids of the selected nodes and first run a MATCH to get hold of these nodes:

Instead, it would be probably more efficient to use WITH and pass the nodes themselves:

WITH $segment
SET segment.length = -segment.length + 1

And the corresponding Java code would look something like this:

Map<String,Object> params = ImmutableMap.of("segment", segmentNode);
gds.execute(query, params);
