[kathap]

This PR adds AliCloud (OSS) support to the Cloud Controller when using storage-cli as the blobstore backend.

• A short explanation of the proposed change: Updates Cloud Controller to route Aliyun blobstores through the new storage-cli client.

• An explanation of the use cases your change solves fog-aliyun is outdated — last updated in 2022, with some transitive dependencies dating back to 2015. This is the Cloud Controller’s side of that migration, ensuring CC can correctly select and use the new storage-cli client for OSS.
