[添加文件]

1.添加CertStore源代码程序文件
[目录层次介绍]
1.conf为配置文件
2.make为Makefile配置文件
3.release为执行make tarball后生成的安装包文件
4.src源代码
src/components 使用的静态库所需的头文件（libevent、openssl、hiredis）
src/inc        系统所需头文件
src/lib        静态库
src/package    安装包临时目录
src/rt         功能函数代码
[编译运行]
1.cd src && make
2../cert_store --debug[release/deamon]
[安装包使用]
1.cd src && make tarball
2.cd release (获取安装包)
2.1.tar -zxvf xxxx.tar.gz
2.2 cd xxx.tar.gz && make install
[版本问题]
1.证书生成代码屏蔽（未调通）
2.Redis超时处理未完成
3.连接响应断开后，资源未释放
