    Reject boot request for unsupported images

    Nova has never supported direct booting of an image of an encrypted
    volume uploaded to Glance via the Cinder upload-volume-to-image
    process, but instead of rejecting such a request, an 'active' but
    unusable instance is created. This patch allows Nova to use image
    metadata to detect such an image and reject the boot request.
