FYI, I updated mininet image for this test to use latest OVS 2.5. Hopefully this adds more stability.

The bug will remain open until we understand why Beryllium (old plugin) can scale up to 500 switches with no issues and Boron cannot.

After changing to OVS 2.5, I get almost fix max=400 switches which I think it has been always the limit for Li plugin, so reducing the priority to normal in case you want to continue with this bug.

FYI the ERROR I see when # of switches ~450 is:

This is fixed now. We see 500 switches (max in the test) for most of the time.
