    Switch to dictionary for iptables find

    The code to find the matching entry was scanning through a
    list of all rules for every rule. This became extremely slow
    as the number of rules became large, leading to long delays
    waiting for firewall rules to be applied.

    This patch switches to the use of a dictionary so the cost
    becomes a hash lookup instead of a list scan.
