Refactor vCenter snapshot handling and VM operations

- Introduced a new method `resolveVCenterFromProduct` in `SnapshotService` to streamline vCenter resolution from product data.
- Updated `CreateSnapshot`, `RemoveSnapshot`, and `RevertSnapshot` jobs to utilize the new vCenter resolution method.
- Enhanced the `VmController` to support UUID-based service identification for VM operations.
- Added new actions for changing VM IP and RDP port, encapsulating the logic for these operations.
- Improved error handling and logging for VM operations, including detailed responses for API consumers.
- Removed unnecessary relationships in model queries to optimize performance.
