[BUG] ilogtail 插件 input service_kafka报错

[codingdancer]

Discussed in #459

^{Originally posted by codingdancer October 13, 2022}
docker环境下 采集kakfa 数据 ，发现如下问题：
1.topic 配置问题
应该使用key 为Topics 配置，否则会报找不到topic
2.sarama-cluster 消费问题
具体报错信息

ilogtail exited unexpectedly

docker 配置如下：

enable: true
inputs:
  - Type: service_kafka
    Version: 2.1.1
    Brokers: 
      - 10.71.48.62:9092
    ConsumerGroup: skyeyeResult
    Topics:
      - test
    ClientID: ilogtail
flushers:   
  - Type: flusher_kafka
    Brokers: 
      - 10.71.48.62:9092
    Topic: bmw_bms_collector_rsk

解决方式 ： 替换consumer.go 452行代码

	ticker := time.NewTicker(c.client.config.Consumer.Offsets.AutoCommit.Interval)

你好，文档确实是错了，代码也可以和文档的fix一起提交PR上来。
