OK not used if SSL not configured. If SSL configured uses the 
credentials pointed to by
--private-key etc, which can be in the Open_vSwitch, OVN_Northbound or 
databases in the specified table or else where. So wondering are there 
helper tools
(ovn-ctl /ovs-ctl ?) to set these DB tables or are they 
created/manipulated by modifying the
DB directly. Guess read the manual.
