Merging fix for CES-401 [1/1]

Merging in the fix for CES-401 from mesa 1.6.1:

This change fixes bug CES-401: Quantum networking not recovering from compute node reboot

There is a known problem with quantum running in OVS/GRE mode where the networking for VM instances hosted on nova compute nodes is broken when the compute nodes are rebooted.

OpenStack provides a quantum-ovs-cleanup script that must be run on compute node bootup to clear out changes to the bridges that OVS makes automatically when the node is booted.

This change adds execution of that script to correct the bridges.
