DjangoObjectType fields description

Нужно добавить парсер параметра verbose_name Field-ов из модели ORM Django в description Field DjangoObjectType-a.
Чтобы это выглядело примерно так:

```python
class User(AbstractUser):
"""Custom user model."""

email = models.EmailField(verbose_name='Email address', unique=True)
avatar = models.ImageField(verbose_name='Avatar image', null=True, blank=True, storage=S3AvatarStorage())
username = models.CharField(verbose_name='Username', max_length=150, unique=True, null=True, blank=True)

class UserType(DjangoObjectType):
"""GraphQL type based on user model."""

avatar = graphene.String(name='avatarUrl')
username = graphene.String(description='Login for authentication') # В случае если хотим кастомизировать описание для поля

class Meta:
model = User
get_description_from_model = True
```

Start by locating the DjangoObjectType field-generation path and its Meta option handling. Check how model Field verbose_name and explicitly declared Graphene field descriptions are represented, then verify that generated descriptions use verbose_name while explicit descriptions remain unchanged.
