    Adds evacuate method to compute.api
    
    Added decorator to check whether the vm is suitable to be evacuated.
    The decorator validates that vm host is down.
    The new evacuate method calls rebuild with the recreate flag and
    specified target host.
    
    This implements blueprint rebuild-for-ha
