    rebuild-for-ha core functionality
    
    This implements blueprint rebuild-for-ha
    
    Evacuation of VM from a failed host for HA.
    New api supports recreate/rebuild modes. With shared storage,
    VM is recreated on the target from disk.
    Otherwise, rebuild from original image is performed.
    
    * new evacuate method in compute.api
    * new recreate flag in rpcapi.rebuild
    * added functionality to clean evacuated instances on host init
    * change in manager.rebuild to rebuild instance using existing disk
