Testsuite: generate required OpenVPN key(s)

Now all the loaded configs will support OpenVPN based interfaces, too.
All required keys are now generated so the loaded configurations can use:

- /config/auth/ovpn_test_ca.pem
- /config/auth/ovpn_test_server.pem
- /config/auth/ovpn_test_server.key
- /config/auth/ovpn_test_dh.pem
- /config/auth/ovpn_test_site2site.key
- /config/auth/ovpn_test_tls_auth.key
