client: Add warning prompt on dangerous commands Added a warning and confirmation prompt for the following commands: * deactivateStorageDomain * deleteImage * deleteVolume * deleteVolumeByDescr * destroyStoragePool * extendStorageDomain * extendVolume * forcedDetachStorageDomain * formatStorageDomain * mergeSnapshots * moveImage * moveMultiImage * reconstructMaster * releaseDomainLock * removeVG Also added '--force' flag to bypass warnings and prompts (intended for scripts).
