Fix for CES-401: Quantum networking not recovering from compute node reboot

Symptom: When a compute node is rebooted, quantum networking fails for all
VM instances that are hosted on it.

Resolution: This is a known issue with quantum.  An OVS cleanup utility
was added to resolve this.  The utility need to be run on the compute
node on bootup.
