Steps:
1. Update default security group
2. Create router01, create networks.
3. Launch vm1 in net01 network and vm2 in net02 network
on different computes.
4. Go to vm1 console and send pings to vm2
5. Ban ovs-agents on all controllers, clear them and restart
service neutron-plugin-openvswitch-agent on all computes.
To do this, launch the script against master node.
6. Wait 30 seconds, send pings from vm1 to vm2 and
check that it is successful.
Duration 10m
