> Custom WAL archive cleaner (BackupLogCleaner).  We need to keep WAL files in archive
until they either get copied over to backup destination during an incremental backup or full
backup (for ALL tables) happens. This is tricky, but is doable. Backup-aware WAL archiver
cleaner should consult hbase:backup to determine if WAL file is safe to purge.
