    Add new debugging logs for ``ARPSpoofTestCase``

    In case of error, the class ``ARPSpoofTestCase`` now provides the IPv6
    and IPv4 neigh list of the source and destination ports.

    This patch also adds a retry branch on the ``assert_ping`` method. If
    enabled, if the first ping command fails, the method will try to execute
    it again.
