Merge branch 'tiexin.yang' into 'master'

java-nginx支持参数传递java-gateway ip

## 支持通过参数传递java gateway ip列表进行nginx配置文件同步

> 已通过线下环境测试，是否传递参数 apigateway upstream都可以正常获取到默认/指定 java-gateway ip列表并应用配置文件

> 修改role openresty不影响java-nginx以外其他playbook
>> [root@ip-172-31-2-77 playbooks]# grep -ir openresty .

>> ./java-nginx.yml:    - openresty
