Issue title: addon-info: Add support for Vue
 Issue body: ### Issue details
This issue is feature request for adding support Vue component on `@sotrybook/addon-info`

Also, it would be nice if there is feature for choosing which component to be documented, something like

```js
withInfo({ component: MyComponent })(() => /** story */)
```

---
### Additional
Currently, I'm using storybook to showcase a Vue component in [mvce](https://stackoverflow.com/help/mcve) style like [here](https://github.com/DrSensor/vue-annotator/tree/master/src/stories). 
Because it's more comfortable writing scenario/use-case in `.vue` SFC format, so I implement it via this way:

1. register each scenario as [story](https://github.com/DrSensor/vue-annotator/blob/6ce1e3c1ede49f300a6fc0d2ca861f02e06532f2/src/stories/index.js#L61)
2. write [scenarios](https://github.com/DrSensor/vue-annotator/tree/master/src/stories/BasicShape) in `.vue` SFC format
3. register [my reusable component](https://github.com/DrSensor/vue-annotator/blob/6ce1e3c1ede49f300a6fc0d2ca861f02e06532f2/src/stories/BasicShape/Rectangle.vue#L25) on each scenario

In short: 
`src/stories/index.js` <- `src/stories/story/Scenario.vue` <- `src/components/MyComponent.vue`

 Comment 2: Not, closing!!!
 Comment 3: #1501 should probably be done before adding support for more frameworks
 Comment 4: I would imagine info support for vue to be in a new addon instead of adding it to the existing info addon. There are some pretty significant differences between the two frameworks that I think it justifies splitting them.
 Comment 5: Something like `import { withInfo } from '@storybook/addon-info/vue'`?
