Handle case with no server or no client OpenVPN
If there are OpenVPN servers but not clients, this warning is emitted:Warning: Invalid argument supplied for foreach() in /etc/rc.openvpn on line 55This fixes handles that case, and the case of OpenVPN clients but no servers.
We should also resync openvpn clients since they can use gateway groups too.
Make the openvpn resync less intrusive, only trigger this if the OpenVPN interface is actually a gateway group name. Otherwise we skip.
Remove this filter configure call, something else will take care of this and we don't need to do that here.
Fix perms on rc.openvpn, seems to work with that set.
