chain for loop was using iteritems which isn't available in Python3
anymore and was throwing an exception when run with Salt on Python3.

There is a way to manage tables in rules, but there is no way to
manage tables for chains when setting policy.

Looks like pillar structure is bad from the beginning and to
not break backward compatibility, as same chain names may occur in
different tables, so it is proposed to check if 'chain.policy' is
map. And if it is, specific policies would be ensured for specific
tables, otherwise table 'filter' would be used as a fallback.

To ensure chains in specific tables we iterate over all rules in
each chain.

This hash is valid:

parameters:
  iptables:
    service:
      enabled: true
      chain:
        OUTPUT:
          policy: ACCEPT
        FORWARD:
          policy:
          - table: mangle
            policy: DROP
        INPUT:
          policy:
          - table: nat
            policy: ACCEPT
          rules:
          - jump: ACCEPT
            protocol: icmp
        POSTROUTING:
          rules:
          - jump: MASQUERADE
            protocol: icmp
            out_interface: ens3
            table: nat

If some rules references other chains that are not yet present
state fails. Make sure all chains are created before any rules by
configuring requirement constraint.

* Allow custom chains to be present, other than the INPUT, FORWARD, OUTPUT default chains.

* Adding missing endif

* Require the packages to be installed first.

* Test should use rules as key, not rule.

* Making it a array list, instead of a dict.

* convert rules to a list instead of a dict.

* Only if policy is defined, include this statement.

* Only ensure chains if not container :)

* The chain is only ensured if we are not a container.

* Do not run at all for containers.

Closes: #2 

* add the option to specify the family per rule to support ipv6

* include policy updates for ipv6

* update documentation to mention ipv6

* Make ipv6 optional; remove spurious tabs from the readme.

* set ipv6 policies only if ipv6 is enabled on the host and not explicitly turned off for this service
