Description of problem:

Ansible roles can not be imported when 'roles_path' is defined in /etc/ansible/ansible.cfg

Version-Release number of selected component (if applicable):
I have tested on 6.7 and 6.8

How reproducible:
100%

Steps to Reproduce:
1. Edit /etc/ansible/ansible.cfg by defining the 'roles_path' variable.
Eg.: roles_path = /root/git/ansible/roles

2. Try to import ansible roles by going to Satellite webUI -> Configure -> Roles(under Ansible section)

Actual results:
we get a message saying "No changes in roles detected on <sat/capsule>"

Expected results:
The Ansible roles should be found under /etc/ansible/roles and listed in the WebUI to be imported.

Additional info:
It seems the /etc/ansible/ansible.cfg takes precedence over /etc/foreman-proxy/ansible.cfg
in '/opt/theforeman/tfm/root/usr/share/gems/gems/smart_proxy_ansible-3.0.1/lib/smart_proxy_ansible/roles_reader.rb'
