CVS Tags: smeserver-openvpn-routed-0_1_6-5_el7_sme, smeserver-openvpn-routed-0_1_6-3_el7_sme, smeserver-openvpn-routed-0_1_6-6_el7_sme, smeserver-openvpn-routed-0_1_6-4_el7_sme, smeserver-openvpn-routed-0_1_6-7_el7_sme, HEAD 
* Thu Apr 01 2021 Jean-Philippe Pialasse <tests@pialasse.com> 0.1.6-3.sme
- autoconfiguration if openvpn-bridge is isntalled and configured [SME: 11336]
- reworked systemd unit and scripts
- new property HMAC forced to SHA256, instead of insecure default SHA1 [SME: 9925]
- Cipher now enforced to AES-128-CBC, instead of insecure default Blowfish [SME: 9919]
- possibility to exclude networks to push [SME: 10548]
