- Add Azure Blob Storage support with container operations
- Add Google Cloud Storage support with bucket operations
- Update CloudStorage API to support azure and gcp providers
- Add config field to CloudStorage spec for provider-specific options
- Add comprehensive unit tests for both Azure and GCP implementations
- Update CRD manifests with new provider options
