OpenStack Compute (Nova) Folsom, Grizzly, and Havana does not verify the virtual size of a QCOW2 image, which allows local users to cause a denial of service (host file system disk consumption) by creating an image with a large virtual size that does not contain a large amount of data.

- Ensure we don't boot oversized images (CVE-2013-4463 and     CVE-2013-2096)

    - Require ipmitool for baremetal driver (#1022243)

    - Remove cert and scheduler hard dependency on       cinderclient (#1031679)
