Although nova is setting the permissions on block devices, sometimes it fails, and that results in an instance failing to launch. It is only an issue for 3-part images, and images accessed through block devices. This patch adds an udev rule, so that devices will be accessible. fixes bug 1218251 Change-Id: I837ea515457fbfc50e9ce138ea9de9db12baa8be
