fix: apply change set concurrency

[mfiedorowicz]

This pull request includes significant changes to the netbox_diode_plugin/api/views.py file. The changes focus on improving the handling of object types and serializers, adding new methods to manage nested options, and ensuring proper error handling.

Key changes include:

Improvements to object type handling:

• Modified _get_object_type_model to return both object_content_type and its model class.
• Updated various methods to use the returned model class from _get_object_type_model instead of directly accessing object_type_model. [1] [2] [3]

Enhancements to serializer methods:

• Split _get_serializer into separate methods _get_serializer_to_create and _get_serializer_to_update for better readability and maintenance. [1] [2] [3]
• Added _get_fields_to_find_existing_objects to handle nested options and specific object type fields.

Error handling and object existence checks:

• Improved error handling for non-existent objects in _get_serializer_to_create, _get_serializer_to_update, and other related methods. [1] [2]
• Added a check to skip creating an object if it already exists during the post method.

Minor adjustments:

• Updated _get_index_class_fields to handle the TagIndex registration in the netbox_diode_plugin.
• Added _add_nested_opts method to recursively add nested options to fields.
