LambdaFunction does not map attrs of skeleton sublabels

[josiahls]

Actions before raising this issue

• I searched the existing issues and did not find anything similar.
• I read/searched the docs

Steps to Reproduce

1. Create skeleton
2. Add confidence attr to individual points
3. Have nuclio function return a skeleton with keypoints that have confidence sublabels
4. CVAT ui, the confidence labels will be unchanged / have the default values.

Expected Behavior

nuclio functions should be able to return skeletons with sublabels that have attrbibutes.

Possible Solution

Update views.py:
https://github.com/josiahls/cvat/blob/patch-1/cvat/apps/lambda_manager/views.py

def update_mapping(_mapping, _model_labels, _db_labels):
    logger.debug("Starting update_mapping with _mapping: %s, _model_labels: %s, _db_labels: %s", _mapping, _model_labels, _db_labels)
    copy = deepcopy(_mapping)
    
    for model_label_name, mapping_item in copy.items():
        try:
            logger.debug("Processing model_label_name: %s", model_label_name)
            md_label = next(filter(lambda x: x['name'] == model_label_name, _model_labels))
            db_label = next(filter(lambda x: x.name == mapping_item['name'], _db_labels))
            mapping_item.setdefault('attributes', {})
            mapping_item['md_label'] = md_label
            mapping_item['db_label'] = db_label
            
            logger.debug("Mapped md_label: %s to db_label: %s", md_label, db_label)

            if md_label['type'] == 'skeleton' and db_label.type == 'skeleton':
                mapping_item['sublabels'] = update_mapping(
                    mapping_item['sublabels'],
                    md_label['sublabels'],
                    db_label.sublabels.all()
                )
                logger.debug("Updated sublabels for label: %s", model_label_name)

                # Ensure sublabel attributes are also mapped
                for sub_md_label in md_label['sublabels']:
                    sub_md_name = sub_md_label['name']
                    sub_db_label = next(filter(lambda x: x.name == sub_md_name, db_label.sublabels.all()), None)
                    if sub_db_label:
                        sublabel_attr_mapping = {
                            attr['name']: attr['name'] for attr in sub_md_label['attributes']
                        }
                        mapping_item['sublabels'][sub_md_name]['attributes'] = sublabel_attr_mapping
                        logger.debug("Mapped sublabel attributes for sublabel: %s - %s", sub_md_name, sublabel_attr_mapping)
        except Exception as e:
            logger.error("Error processing label: %s, Error: %s", model_label_name, e)
    
    logger.debug("Finished update_mapping with result: %s", copy)
    return copy

Context

nulcio autolabelling for skeletons that have keypoints with attributes.
