This should resolve#1011 which provides an ip6tables resource to test IPv6
iptables rules. This is essentially a copy of the iptables resource with a few
renames.
In addition, I've pulled in the integration tests for iptables into ip6tables
and enabled it on docker so that it properly gets tested regularly. The test
cookbook recipe has been updated to support all of the current platforms that
are being tested.
