Stage out to organize files by collection id 

https://github.com/unity-sds/unity-data-services/blob/develop/cumulus_lambda_functions/stage_in_out/upload_granules_by_complete_catalog_s3.py#L65

if we want to keep the collection:granule_id format, then we need to do:

`s3_url = self.__s3.upload(asset_href, self.__staging_bucket, f'{self.__collection_id}/{self.__collection_id}:{current_granule_id}', self.__delete_files)`
