Database driver configuration options #36
Description
There is a problem accessing Neo4j Aura databases--the connection times out and closes if unused after 60 minutes. It's necessary to trap the org.neo4j.driver.exceptions.SessionExpiredException and close and reopen the connection to solve this. We don't automatically close the driver after each query because doing so seems to incure a significant memory leak (about 500k bytes each time).
Neo4j says to configure the driver for a 50 minute max lifetime: here. This is done by calling with the Config builder's withMaxConnectionLifetime method, but that isn't exposed in the neo4j-clj.core/config function.
There are a large number of Config builder functions--is it worth supporting more of them in config or would it be better to delegate that responsibility to the calling program and expose a connect variant that accepts a built Config object?
