improve neo4j testcontainers performance

[jexp]

Michael Simons Here’s a tip you can try to make your tests faster if you’re using the Neo4j test container:

Neo4jContainer<?> neo4jContainer = new Neo4jContainer<>()
	.withTmpFs(new HashMap<String, String>() {{
		put("/log", "rw");
		put("/data", "rw");
	}});

it will use your tmpfs filesystem for the data and log folders.
(On JDK11+ don’t follow my example with the ugly double brace initialization of the map, though and use Map.of instead… Keys are the paths, values the parameters)
