Title: Make a fields.gridfs()

Make a gridfs field, like `fields.binary` but stored in MongoDB backend.

We could do:

```python
from mongodb_backend import fields as mongodb_fields

...

_columns = {
'some_binary_field': mongodb_fields.gridfs('Label')
}
```

This should save the object id in the field of postgresql table and the content in gridfs.
