Sync Finetune Job Status

@TODO THIS WOULD BE REMOVED EVENTUALLY
(REPLACED BY finetune_job_sync_scheduler in services/workers/finetune_processor/consumer.py)

This function is used by Airflow to sync Finetune job status on OpenAI.
This method works by fetching all finetuned models for an organisation with status BUILDING,
and then schedules Kafka events (post to SUBMIT_FINETUNE_KAFKA_TOPIC) in a parallel manner.
