### Describe the bug

Module http adapter is not beind exported, so I cannot force axios to use the http adapter instead of xhr

### To Reproduce

```js
const axios =  require('axios');
const url = 'https://catfact.ninja/fact';
axios.get(url, {
  adapter: require('axios/lib/adapters/http'),
}).then(console.log).catch(console.log);
```
or 
```js
const instance = axios.create({
  adapter: require('axios/lib/adapters/http'),
})
```
It works using axios@0.27.2




### Expected behavior
