hls/http/rtmp load test tool base on st(state-threads), support huge concurrency
服务器负载测试工具(st-load)：
- 模拟huge并发：2G内存就可以开300k连接。基于states-threads的协程。
- 支持HLS解析和测试，下载ts片后等待一个切片长度，模拟客户端。支持HLS点播和直播。
- 支持HTTP负载测试，所有并发重复下载一个http文件。可将80Gbps带宽测试的72Gbps。
- 支持RTMP流测试，一个进程支持5k并发。使用nginx-rtmp的协议直接将chunk流解析为messgae。
- RTMP协议使用高性能服务器SRS(SimpleRtmpServer)的协议栈，1000个客户端只需要使用30%CPU。
TestEnvironment: 24CPU, 80Gbps Network, 16GB Memory
Server: NGINX HLS
Result: 90% bandwith, 72Gbps
