Migrated from https://git.shore.co.il/nimrod/resolver.

This reverts commit a90efee1. Builds
break when changing only the depending image.

Set the dependencies between jobs (for images that depend on other
images in this repo).

From https://git.shore.co.il/shore/workbench.

I want to run it remotely on my Kodi.

Those jobs are not always in the workflow and that makes the workflow
invalid in those cases. Since the build and push already happens before
those jobs will use the newer base images anyway.

Some images are base images for other images. There's a need to build
the base images first.

- Use the containerfiles templates.
- The repo was renamed as part of a refactor.

Without the CONTEXT variable, the rules for push jobs was broken and
always triggered. This also pulled in the dependency jobs. I don't see a
way to avoid defining the CONTEXT variable in both build and push jobs.

Same as the buster image, but bullseye.

Both latest and buster tags.

- Notify on scheduled pipeline failures.
- Seperate the IMAGE and CONTEXT variables. Allow building where the 2
don't match (planning for httpd/buster and httpd/bullseye).
