CLOUD: Add GoogleDriveListDirectoryRequest

When listing directories, you get a list of StorageFiles, which path()
is actually Google Drive id. Thus, if you list a directory recursively,
you won't be able to determine whether all files are within one
directory or have some hierarchy. I'd fix that as soon as it would be
needed.
