Ansible Smart Proxy not Processing Variables

When importing variables on an Ubuntu 16.04 host, no variables are found.

Expected outcome:
Variables are found and imported

Foreman and Proxy versions:
Foreman: 1.21.0
Foreman-Proxy: 1.21.0
Foreman and Proxy plugin versions:
Ansible Smart-proxy: 2.1.0
Ansible Plugin: 2.3.1

Other relevant data:
I noticed that there is a new patch release for the ansible smart-proxy, which has been built and released for CentOS, but not Ubuntu. Also adding the variables_extractor.rb from 2.1.1 the proxy is able to find the variables, although it fails when there is a blank defaults file.

We investigate in, the version should be bumped in deb repositories too.

Looks like this fixed it.
