I wonder would it be better if the ovn-nbctl Port Group commands are as 
follows:

pg-create group [ports]
      Create a port group named 'group' with a list of optional Logical 
Switch ports,
      "port1 port2.." where port1, port2 etc are Logical Switch port names.

pg-del group
      Delete the named port group 'group'

pg-add-ports group  [ports]
        Add the named Logical Switch ports to the 'group' Port Group, 
eg. "port1, port2"

pg-del-ports group [port]
       Remove the named Logical Switch ports to the 'group' Port Group, 
eg. "port1, port2"
