OpenFlow controllers work with OpenFlow switches (bridges).  If you
don't have a switch, then it doesn't make any sense to tell OVS to
connect to a controller.

There's a separate project developing OF-CONFIG for OVS.  See
https://github.com/openvswitch/of-config.  But Open Daylight also
supports OVSDB, which is the OVS native configuration protocol, so it
would be easier for you to use that.
