Add blubber and deploy the images
This includes using the image for tests, and for publishing the image on toolsbeta (for now, testing)
The expected flow is:
- When a merge request is created -> pushes to toolsbeta-harbor with tag dev-mr-#MR_NUMBER
- Manually you can deploy on toolsbeta, creating a new image with tag mr-#MR_NUMBER
- Manually you can deploy on tools, creating the image with tag mr-#MR_NUMBER
Using the MR_NUMBER instead of the commit hash as that is known before-hand, allowing to update the values files in the same MR.
This depends on !5 (merged)
