    Collect ip6tables for logging purposes

    Currently SM troubleshoot does not collect ip6tables statistics, only
    iptables. This change adds this information for debugging.

    Tesplan
    [PASS] execute "collect all" and check that the sm.info file contains
           the output of ip6tables -nvL
