Add support for Debian

[kienanstewart]

Affected Puppet, Ruby, OS and module versions/distributions

• Puppet: 5
• Ruby: 2.5
• Distribution: Debian Buster
• Module version: 1.0.0

Description

There are a few changes to make the module work on Debian

• the nftables configuration file should /etc/nftables.conf instead of /etc/sysconfig/nftables.conf
• the directory /etc/nftables is not created by the Debian package for nftables (managing it in the module would work?)
• firewalld is not installed by default, so should be false instead of mask on Debian systems by default
• (optional) for Debian Stretch, the version of facter shipped w/ the OS does not use structured facts. If it is desired to extend support to Debian Stretch, that case should be handled as well.

I have a WIP branch dev for which I will open a PR.

thanks

When people continue to push things on the outstanding pull request and make it possible to merge: #66 . This is a free software project and not a product, if you want something in either contribute or wait (patiently). Thank you.

I believe that's done via #134.
