From: Jan Provaznik <[email protected]>
This is first shoot in image/template models refactoring, lotof TODOs
- method for uploading template to warehouse is stubbed, expects uri to template
to be returned
- suppose image uuid is generated by aggregator for now when image is created
in CE
- when image factory builds image, image's status should be updated
- image_providers table represents images uploaded to providers, suppose user
can create instances only from uploaded images
- instance is now connected with image_provider instead of image
- when image is uploaded to provider, image_providers mapping should be updated
