Provides a client service for managing connections to a Neo4J 4.X or newer database. Configuration information for the Neo4J driver that corresponds to most of the settings for this service can be found here: https://neo4j.com/docs/driver-manual/current/client-applications/#driver-configuration. This service was created as a result of the break in driver compatibility between Neo4J 3.X and 4.X and might be renamed in the future if and when Neo4J should break driver compatibility between 4.X and a future release.
