r/aws_backup_plan: Prevents the sending of empty lifecycle attributes

Closes #8151 Lifecycle policies contain settings for deleting backups, and for moving them to cold storage. A backup with cold storage enabled can not have a deletion value lower then 90 days. So to prevent this AWS allows setting ColdStorageAfter to Never by not setting a value for ColdSorageAfter. This change add logic to ensure ColdSorageAfter and DeleteAfter only get sent within the API request if the values are not empty and greater than 0.
