Filter Only The Serializable Fields

Api Platform is the best API Framework Ever is used. It's great framework.

Recently, when we activate the filter feature without specific fields defined, for example
```
bisnis.filter.order_filter:
parent: 'api_platform.doctrine.orm.order_filter'
arguments: [ ~ ]
tags:
- { name: 'api_platform.filter', id: 'order.filter' }
```

The Api Platform (see Api Doc) processing all fields based on doctrine metadata even the fields is not displayed. Is good choice to filter only the fields that displayed by serialization not all fields.
