Bug Description

In some cases firewall rules for IPv4 and IPv6 should not be the same. Two examples:

1. DHCPv6 uses UDP port number 546 for clients and port number 547 for servers. While DHCP (v4) uses UDP port number 67 for clients and port number 68 for servers.
2. For IPv4 protocol 'icmp', while for IPv6 'ipv6-icmp'

Currently the icmp difference is handled in puppet-tripleo[1], but for DHCP TrieplO currently open port 67 and 68 for both IPv4 and IPv6 and it does not open port 546 and 547 at all.

puppet-tripleo should support setting firewall rules for either IPv4 or IPv6 if the rule defines the ip_version. For rules not providing this info the current behaviour of adding the rule to both IPv4 and IPv6 firewall should be maintained.

    Add DHCPv6 rules + set ipversion for dhcp rules

    Use the ipversion parameter for firewall rules to contain
    rule creation in either iptables or ip6tables. Add rules
    in ironic-inspector and neutron deployment template to
    add rules for DHCPv6 in ip6tables.

    DHCPv6 relay and DHCPv6 server both use port 547 so 547
    need to be open for both INPUT and OUTPUT.
