Feature: support for vite2.0

[wulisensen]

希望能支持vite2.0

[jaywcjlove]

@wulisensen 我不太明白需要如何兼容

使用下面方法启动一个服务 vite 也是可以用的吧

{
  "name": "base-example",
  "scripts": {
+    "api": "mocker ./mocker"
  },
  "devDependencies": {
+    "mocker-api": "2.8.2"
  },
+  "mocker": {
+    "port": 7788
+  },
  "license": "MIT"
}

@wulisensen Made mocker lib compatable with Vite https://github.com/avin/fake-api-middleware
Mocks structure is very similar to mocker-api
