    Adds option to rebuild instance with exisiting disk
    
    Evacuation of VM from a failed host for HA.
    New api supports recreate/rebuild modes. With shared storage,
    VM is recreated on the specified target from existing disk.
    Otherwise, rebuild from original image is performed.
    
    * new recreate flag and target host in rpcapi.rebuild
    * change in manager.rebuild to rebuild instance using existing disk
