tested this on voxpupuli/puppet-nginx#1492

I'm not strictly opposed to this, but I'd like to rant about something.

Right now these are only installed using SSH so installing SSH over SSH doesn't make sense. beaker-docker is in a weird state that it mostly duplicates this, but Arch reuses it. In #1718 I started an effort to make this easier to reuse. That's where I'd like to end up.

With that in mind, 👍

Btw, normally net-tools is only installed via beaker-hostgenerator (see https://github.com/voxpupuli/beaker-hostgenerator/blob/master/lib/beaker-hostgenerator/data.rb). Beaker itself doesn't need net-tools and I already explained why openssh here doesn't make a lot of sense.
