feat: Add storage management for VM creation and resizing

- Introduced storage parameter in VmCreateRequest and VmResizeRequest models.
- Implemented storage validation to ensure minimum and maximum limits.
- Enhanced CLI to support storage options during VM creation and resizing.
- Updated lifecycle management to handle pending resize operations for VM resources.
- Added methods for resizing VM disks and validating storage capacity.
- Updated API endpoints to accommodate new storage functionality.
- Refactored related validation and configuration logic to support storage management.
