"microstack.ovs-dpctl dump-flows"does not appear to work

[Paul Goins]

I'm trying to prepare some training materials for use inside the BootStack team, leveraging microstack to ramp team members on OVN via the OVN OpenStack tutorial (https://docs.ovn.org/en/latest/tutorials/ovn-openstack.html).

While trying to walk through the tutorial myself, I found that the "ovs-dpctl dump-flows" command does not appear to work. This is what I see:
