Partial fix OPENDJ-662 - Upgrade JE to latest version of JE5, and modify default config settings to latest recommendations / expected machine capabilities.

* db-evictor-lru-only - change to false (depth based then lru) since it exhibits better behavior in partially cached deployments and does not impact cases where the DB is fully cached
* db-log-file-max - increase back to 100MB due to recent improvements in JE which mean that smaller file sizes are no longer needed. Bigger log files means less of them, less frequent fsyncs, and less FDs
* db-checkpointer-bytes-interval - increased to 500MB. The increased recovery time is minimal and a bigger checkpoint interval dramatically reduces the risk of persisting volatile data to disk
* disk-low-threshold - updated to 200MB to align with increased log file size
* disk-full-threshold - updated to 100MB to align with increased log file size
