openvpn@.service script attempts to start openvpn@multi-user and fails.

Error Message:
Options error: In [CMD-LINE]:1: Error opening configuration file:
multi-user.conf


It might be better to have the script read an /etc/sysconfig/openvpn file to
determine which instances to start, because using %i doesn't work.
