argocd+gitlab应用自动发布

# gitlab仓库配置

推荐gitlab创建空仓库后，拉取到本地编辑好以后再提交，不要直接编辑gitlab的yaml文件，因为gitlab在线编辑时，换行与tab空格在argocd上可能存在识别失败，不是标准的yaml文件，无法创建应用。
创建一个最简单的仓库，仅包含应用的yaml文件，文件内容如下

[root@k8s-master test-git]# tree test/
test/
├── manifests
│   └── test.yaml
└── README.md

1 directory, 2 files
[root@k8s-master test-git]# cat test/manifests/test.yaml 
apiVersion: apps/v1

  namespace: default

  selector:
