redis-proxy invalid header type

按照这里的文档配置 redis-proxy, https://pegasus.apache.org/api/redis , redis-proxy 可以正常运行, 但是使用 redis-cli 链接时, 无法读取/写入数据, 并报错:
```

```
`header_type = '*3\0D\0A'` 是 redis protocol 解析 redis command 的内容, 使用 redis-cli 2.8/5.0.4/6.2.6 测试均有问题
pegasus 版本 2.3.0

请问, 有可能是什么原因呢?

Start at the redis-proxy entry point and the configuration linked in the issue, then reproduce with redis-cli 2.8, 5.0.4, or 6.2.6 while capturing the parser logs. Trace handling of RESP headers such as *3\r\n and *5\r\n; done means redis-cli can read and write through the proxy without invalid-header or session-read errors.
