The issue with not being able to show/update/delete non-OVN agents was due to a bug where we would catch KeyError to signal that we should pass the agent request back up to ML2 since the agent wasn't ours, but at some point the exception was changed to an AgentNotFound. This meant that we were only handling OVN agents and never handing control back to ML2 for any others.
