CLI fail to make redis connection on secure TLS connection

Add conf for tls om CLI commands.

    const redisConfig = config.get('isbn:redis');

    if (redisConfig.tls) {
        const tls = redisConfig.tls;

        if (tls.keyFile) {
            tls.key = fs.readFileSync(tls.keyFile);
            delete tls.keyFile;
        }

        if (tls.certFile) {
            tls.cert = fs.readFileSync(tls.certFile);
            delete tls.certFile;
        }

        if (tls.caFiles) {
            tls.ca = tls.caFiles.map(file => fs.readFileSync(file));
            delete tls.caFiles;
        }
    }
    // init redis
    const redisClient = redis.createClient(redisConfig);
