    fencing.py: Adds device option login_eol_lf
    
    This option is used for login method using telnet. By default most of the fence agents
    work with username\r\n but on some devices (e.g. HP iLO MP, sanbox2) it is interpreted
    as there is empty password.
    
    Needed for bz#512947 (sanbox2) and #508722 (fence_ilo-mp)
