Stop ES from redundantly logging to journald

[zwets]

This PR (like #6428 for Kafka) removes the console appender from the Elasticsearch root logger, so as to not duplicate in journald the logging that already goes to log files.

The second commit fixes the issue that cchq ap deploy_db.yml --tags=es_conf doesn't include misc_v{5,7}.yml thus missing most of the ES configuration.
