Michele Baldessari 96cb130c5a Add a script to zero /etc/sysconfig/ip6tables at build time 
In change Iddc21316a1a3d42a1a43cbb4b9c178adba8f8db3 we zeroed out
/etc/sysconfig/iptables, but we did not take care of ipv6. This change
is meant to take of the ipv6 part of the problem.
When including this element we empty the stock /etc/sysconfig/ip6tables
file as shipped by the iptables rpm package. The reason for this is that
puppet firewall has a hard time to cope with exiting rules when
/etc/sysconfig/iptables is populated and the iptables service is not
active. The referenced bug has a full explanation for the problem.

Note that ipv6 is slightly more delicate because we will also need a puppet-tripleo
change that implements the dhcpv6 rule that is contained by default
in /etc/sysconfig/ip6tables:

##iptables

This element installs a single script that consolidates the logic required to handle inserting iptables rules. This script uses the check (-C) argument to check whether a rule matching the specification does exist in the selected chain before inserting it.

RULE: The rule to insert into iptables
