all openvpn parameters should be passed as flags
We want to avoid passing a config file to openvpn binarie, since it opens a vector to attack. Currently we're using a pretty minimal client config, so it won't be too hard to convert all those options to command line arguments.
Check:
- OPENVPN_CONFIG_TEMPLATE in eip.config
- build)ovpn_options in eip.config
