Title: Add requireParameters config option

Add ```requireParameters``` config option, return 400 bad request if required validation failed.
```
config = {
path: "/require-para",
requireParameters: ['name']
}
```

```
GET /require-para
// response
400 {error: "Required parameters(name) not found"}
```

Hope I am not the only one who need this feature, thanks!
