Description Brent Eagles 2015-11-27 16:16:00 UTC 
Cloned from launchpad bug 1515075.

Description:

How to reproduce:
1. Stop the neutron server to simulate it's busy/down
2. Restart an ovs agent.

After the first rpc times out(default to 60 seconds), the agent will delete some of the existing flows.

Expected:
Keep the existing flows to make sure the instances are happy.
