Bug Description

The fix for the Heat bug 1514680 introduced a translation rule that means that the OS::Nova::Server resource now sees only the UUID of the image, even when the image is passed by name. This means that servers will be rebuilt on the next update after uploading new images.

TripleO always keeps the same name when uploading images with the expectation that this will not result in existing servers being rebuilt (however new servers will be created with the latest image).

Change abandoned by Zane Bitter (<email address hidden>) on branch: master
Review: https://review.openstack.org/350145
Reason: Ah yeah, I didn't notice that when the translation rule was added, the code to look up the UUID before creating the server was removed. That's much more difficult to surgically work around in a subclass :(

Marius hit this problem when testing Newton, assigning the rc2 milestone, and also mitaka-backport-potential.

    Ignore changes to images in nova servers

    Override all changes to the image in OS::Nova::Server, so that we don't
    accidently rebuild them.
