vpn_openvpn_client.php and /etc/inc/openvpn.inc
Has checkbox to enable "Infinitely resolve server"
but the resolv-retry infinite config is used also if is a client. This is a client.

In addition, OpenVPN 2.3 has this enabled
by default. I don't see anything here to set it to 0 (zero) to
disable.

To explain a different way, the config.xml has:
<resolve_retry></resolve_retry> while the openvpn$NUM.conf still has:
"resolv-retry infinite".

I suggest getting rid of it of the feature since is default behavior
and is always set here.

Or if you keep make it so unchecked means is "0" and don't set by
default for client too.
