tengine 2.2.2 使用http2协议 下 psot方法超时504；

[maqingshan]

CentOS release 6.6 (Final
Tengine version: Tengine/2.2.2 (nginx/1.8.1)

为了提高系统稳定性，决定从Tengine/2.1.2 升级 到最新版本Tengine/2.2.2 。 但是发现上传服务504；
测试结论：
1：回退到2.1.2 服务正常，仍然使用http2；
2：Tengine/2.2.2 下用http1.1 服务正常；
3：Tengine/2.2.2 下用http2 服务超时，504退出；

同样遇到这个问题，目前我的解决方案是增加client_body_buffer_size,并关闭client_body_in_file_only,感觉问题在于POST数据过大的时候，不能写入缓存。

@maqingshan 相关原因可参考这个 #1109
当前正在升级core代码，届时会支持http2的流式上传功能，从根上解决这个问题。
