Summary:
This pull request refactors the validation logic for several persistent storage command handlers (CreateBucketHandler, GetBucketsHandler, ListFilesHandler, GetFileObjectHandler, UploadFileHandler, DeleteFileHandler). It specifically removes consumerAddress, signature, and nonce from the list of parameters explicitly checked for presence within the validateCommandParameters function for these handlers. This change suggests that the validation of these authentication/authorization-related parameters is now either handled at a higher level in the request processing pipeline or is no longer considered a strict requirement for the structural validity of these specific commands.

Comments:
• [WARNING][security] The parameters consumerAddress, signature, and nonce have been removed from the required validation list for PersistentStorageCreateBucketCommand and similar commands throughout this file. While this might simplify individual handler logic, these parameters are typically crucial for authentication and authorization.

Please confirm that these parameters are indeed validated at a higher level in the request pipeline (e.g., by a middleware or a common authentication handler) before reaching these specific persistent storage operations, or that their absence from this validation step does not introduce security vulnerabilities like unauthorized access or command spoofing. If these checks are not performed elsewhere, this change could pose a significant risk.
