    Disallow resize if image not available

    If a resize is attempted on an instance that was started from an image
    that has since been deleted, a resize will fail. This change makes error
    reporting a bit cleaner.

    This change is needed since in order to actually properly support
    resize/migrate when the image is deleted - it is necessary for nova to keep
    a copy of the image metadata and re-use it in case of migration/resize.

    Fixes bug: 1160773
    Fixes bug: 1177001
