Binding is not failing when ODL L2 is down

[Itzik Brown]

When the ODL L2 agent is down and an instance is scheduled to run on the node with this agent the instance is in 'spawning' state for a long time until it fails.

The expected behavior is in the case the agent is down that the binding will fail and the instance will be rescheduled to run on a different compute node.

Version
========
python-networking-odl-11.0.0-0.20170804111351.a27bd55.el7ost.noarch
opendaylight-6.1.0-2.el7ost.noarch

How to reproduce
================
1. Block the outgoing port 6640 on the Compute node
2. Wait for the agent to be down (openstack network agent list)
3. Launch an instance and verify it's scheduled to be on the above node
4. Verify that the instance is in 'spawning' state and not rescheduled to another node
