(#10690) add port property support to ip6tables

…proto'

This change adds ipencap as a viable option, and adds it to tests as well.

Previously the log_level property was constantly reloading due to the fact
that iptables was converting names to numbers. So unless you were using
numbers in your log_level setting, it was constantly telling you it needed
to be changed.

Now we convert the names to numbers in the munge so when comparing it will
always hopefully match.

Also, the default value when the jump value is 'LOG' is now set to 4 (warn)
based on iptables own defaults.

Previously when hostnames were used in the source and destination properties
they were being converted to IP address by iptables. This meant that later
comparisons were failing because the property in code (a hostname) and the
'real' property returned by introspection (an ip address) were not matching.

This code using the munge facility will automatically detect and convert
hostnames to IP addresses in the type so the comparison works as expected.

The side-effect is that puppet does the hostname to IP conversion, not
iptables.

These facts return the version of iptables or ip6tables by running --version
on the binary in question.
