Brian Rosmaita 963fd8c0f9 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.

The Compute service has never supported direct booting of an instance from
an image that was created by the Block Storage service from an encrypted
volume. Previously, this operation would result in an ACTIVE instance that
was unusable. Beginning with this release, an attempt to boot from such an
image will result in the Compute API returning a 400 (Bad Request)
response.
