actully we do use vsctl at least in ci but it is deprecated.
we are currently using it in ci to workaround a bug in the ovs python bindings.
after the RC period is clear i might revert that since i think the ovs python bidnign are
fixed but im not sure they are fixed in ubuntu 20.04 so i dont want to regress the ci stablity
currently by reverting to the native bindings.
ill update https://github.com/openstack/devstack/blob/master/lib/os-vif#L6 to native
once we are sure https://bugs.launchpad.net/os-vif/+bug/1929446 is fixed in the ovs python bindings.
