**[GSOC][Kvrocks] Support database backup to cloud storage**
### Why this PR?
This is a **Draft PR** for my GSoC 2026 proposal: "Cloud Backup Support for
Kvrocks".
I have started by implementing the configuration infrastructure. This allows
the engine to recognize and validate cloud storage settings before we move to
the integration phase.
The goal is to allow Kvrocks to natively support backups to cloud providers
like S3, GCS, and Azure Blob Storage using Apache OpenDAL.
### What has been implemented:
- **Configuration Registration:** Added new fields (`cloud-storage-type`,
`cloud-storage-bucket`, etc.) to the `Config` class.
- **Validation Logic:** Implemented a field validator in
`initFieldValidator` to ensure only supported cloud backends are accepted.
- **WIP Logic:** I have verified these configurations using `CONFIG GET` and
`CONFIG SET` on a running local instance.
### Next Steps:
1. Integrate the **Apache OpenDAL C++ bindings** via CMake.
2. Implement the `CloudStorage` helper class to handle the actual
upload/download logic.
3. Link the backup/snapshot process to the cloud upload trigger.
I welcome any feedback on the naming conventions used in `config.h` or the
validation logic!
