一般公司都会有线上环境、测试环境(测试环境可能有多套: qa/release等).
同一服务不同环境，使用不同的资源实例，比如机器、数据库、域名等.
因此我们需要先管理环境，之后再把环境与不同服务关联起来.
在这基础之上才能管理服务不同环境的资源.
business/service/models.py
business/service/controllers/environment.py
business/service/apis/environment.py
business/service/urls/environment.py
business/service/urls/__init__.py
business/service/controllers/service.py
business/service/apis/service.py
business/service/urls/service.py
account/controllers/user.py
data/sql/rurality.sql
business/service/models.py:
定义EnvironmentModel，以后会默认有一条线上环境记录，并且不允许删除.
环境的sign正常情况下不允许编辑，只有明确知道在干什么的情况下才行.
business/service/controllers/environment.py
business/service/apis/environment.py
business/service/urls/environment.py
business/service/urls/__init__.py
环境的增删改接口.
business/service/controllers/service.py
business/service/apis/service.py
business/service/urls/service.py
首先我迁移了一下文件位置，把apis、controllers、urls都弄成了目录.
然后里面都添加了服务关联环境的方法和接口.
在删除服务关联环境时，以后会增加不允许删除的判断，但具体不允许删除的限制条件以后再说.
有时候想想，所有服务肯定都有生产环境，那么是不是默认所有服务都有生产环境了呢？
但是我并没有那么做，我是基于所有服务都是新服务，然后从测试环境开始接入的，所以上来并没有生产环境.
(旧的服务接入，就自己创建关联就完事了).
account/controllers/user.py:
给admin用户赋予环境管理的菜单权限.
data/sql/rurality.sql:
最新的sql文件.
src/api/business/environment/url.js
src/api/business/environment/index.js
src/views/business/environment/index.vue
src/views/business/environment/components/ObjDialog/index.vue
src/router/modules/system.js
src/components/Field/EnvironmentField/index.vue
src/api/business/service/url.js
src/api/business/service/index.js
src/views/business/service/components/EnvironmentList/index.vue
src/views/business/service/components/EnvironmentList/components/ObjDialog/index.vue
src/views/business/service/detail.vue
src/api/business/environment/url.js
src/api/business/environment/index.js
src/views/business/environment/index.vue
src/views/business/environment/components/ObjDialog/index.vue
src/router/modules/system.js
环境管理功能界面，一样最后放到了系统设置中.
src/components/Field/EnvironmentField/index.vue:
封装环境选择功能，以后有选择环境的地方，可以直接引入此组件.
src/api/business/service/url.js
src/api/business/service/index.js
src/views/business/service/components/EnvironmentList/index.vue
src/views/business/service/components/EnvironmentList/components/ObjDialog/index.vue
src/views/business/service/detail.vue
在服务详情中增加关联环境的功能，直接复制服务与部门关联的代码替换而成.
现在所有服务详情页的样式只是临时的，以后会有变化.
