Backup and restore scenario
This testcase verifies content preservation after backup and restore operations by booting a server from a restored backup and check the connectivity to it, this will indicate that the image data was preserved. Added: - 'create_backup' method in scenario/manager - 'restore_backup' method in scenario/manager Change-Id: I20ebf2bb2e4950c24d912c24a081dc0ac0101b8d
