Previously the cloud native job log (aka CI live trace) Fog
implementation used the `put_object` and `delete_object` API
calls. These are object-storage specific API calls, and they work for
AWS and Google.

However, Fog has a more general API that works for all providers. We
already use this API for backups. To make live job logs work with Azure,
we use that general API.
