src: make logging level configurable via NM_VPN_LOG_LEVEL
NetworkManager supports enabling logging for VPN plugins via
$ nmcli general logging level KEEP domains VPN_PLUGIN:TRACE
In that case, it will spawn the VPN plugin with NM_VPN_LOG_LEVEL
set to a syslog level. Use that, to enable verbose logging of the
nm-openconnect and openconnect service.
