    xl: Support (by ignoring) xl migrate --live
    
    xm migrate would do non-live migration (effectively, save, transfer
    and restore) by default, unless you specified --live.
    
    xl migrate always does live migration.  Honour (by ignoring) --live
    for compatibility with old callers.  Document this.
    
    (This patch should be backported as far as possible.)
