Description of problem: In case the incremental processing code in ovn-controller hits a bug and the state is inconsistent there's no way to trigger a full recompute that would properly install all flows. Version-Release number of selected component (if applicable): How reproducible: Steps to Reproduce: 1. ovn-appctl -t ovn-controller recompute 2. 3. Actual results: Command doesn't exist. Expected results: The command should run and force a full recompute in ovn-controller. Additional info:
