Describe the bug (描述bug)
http2 简单的get请求报错

To Reproduce (复现方法)
1、编译master版本example下的http_c++
2、运行命令 ./http_client --http_verbose=1 --protocol=h2 https://fapi.binance.com/fapi/v1/time
3、即使代码里加上options.mutable_ssl_options();也一样报错

:method = GET
:scheme = https
:path = /fapi/v1/time
:authority = fapi.binance.com
accept = /
user-agent = brpc/1.0 curl/7.0

Expected behavior (期望行为)
正常返回{"serverTime":1689213610168}，和去掉protocol=h2一样

server端可能开启了alpn协商，默认处理http协议，不具备协议自动识别能力。
需要SSL扩展进行协商才能通过h2访问，详见#1991 中的nginx例子

恩，看了一下#1991issue，是不是意味着需要等框架支持alpn后才支持这样调用？

嗯，是这样的
