This commit allows to configure suricata to monitor traffic from or to
OpenVPN tunnels. This includes the RW server and all established N2N
connections.
Because the RW server and/or each N2N connection uses it's own tun?
device, it is only possible to enable monitoring all of them or to disable
monitoring entirely.
Fixes #12111.
