add FreeBSD support

[fraenki]

• Add support for the FreeBSD operating system
• Make the "root" group configurable (it's "root" on Linux, "wheel" on FreeBSD)
• Tested on Puppet 5.x, change metadata.json accordingly

Thanks for your PR! I'm excited about adding new OSes. I am going to try and get this merged first, so bear with me: #38

I may need you to rebase after that.

Looks like you didn't modify the files that the tests are complaining about. I need to get some things updated so the test pass. I wouldn't worry about it at this point.

Hi @edestecd, we plan to continue the maintenance of this Puppet module. Would you be interested to transfer it to us or to voxpupuli? If not, we would continue work on our fork instead. Please let us know.
