This is for logical volume download and upload testing. * using download and upload API under class virStream. they are functions act as same with download/upload APIs under class virStorageVol, just different entrance. * using logical volume specified xml to create volume. no need to provide volume format. * check method is the same with dir vol download/upload cases.

The testcase cases/storage_logical_vol_upload_download.conf couldn't run directly. It'd better that we can check the testing environment first, then decide to run it or not.
