github webkook for jenkins

当不使用 multi pipline 的时候 ，配置 hook: 

```
如果用户名有 @ 符号，转码成 %40 
这样可以在命令行调用：
curl -X POST https://aaa%40bb.cc:115xxxxxxxxxxxxxxxxxxxxxx5bxx@my.job.host/job/my-job-one/build


git webhook 则直接使用以下地址： 
https://aaa%40bb.cc:115xxxxxxxxxxxxxxxxxxxxxx5bxx@my.job.host/job/my-job-one/build

```
