Add 'get_absolute_url' as a option for Django projects

[DmytroLitvinov]

Is your feature request related to a problem? Please describe.
According to Django's default coding style there is a next order of model inner classes and standard methods:

• All database fields
• Custom manager attributes
• class Meta
• def str()
• def save()
• def get_absolute_url()
• Any custom methods

Describe the solution you'd like
I would like to specify get_absolute_url after save or delete option so it will be like next configuration:

class_attributes_order =
    field,
    meta_class,
    nested_class,
    magic_method,
    save,
    delete,
    get_absolute_url,
    property_method,
    static_method,
    class_method,
    method,
    private_method
