/**
 * Simple handler wrapper that deduplicates log records across multiple requests
 *
 * It also includes the BufferHandler functionality and will buffer
 * all messages until the end of the request or flush() is called.
 *
 * This works by storing all log records' messages above $deduplicationLevel
 * to the file specified by $deduplicationStore. When further logs come in at the end of the
 * request (or when flush() is called), all those above $deduplicationLevel are checked
 * against the existing stored logs. If they match and the timestamps in the stored log is
 * not older than $time seconds, the new log record is discarded. If no log record is new, the
 * whole data set is discarded.
 *
 * This is mainly useful in combination with Mail handlers or things like Slack or HipChat handlers
 * that send messages to people, to avoid spamming with the same message over and over in case of
 * a major component failure like a database server being down which makes all requests fail in the
 * same way.
