task: Create useful image

[wdoekes]

• [ ] We'll want to set the build version / build number to something we can remember. Including whether this is a debug build or not.

• [x] For now, we'll want debugging support on.

  • INSTALL_DEBUG_TOOLS = y
  • #SONIC_DEBUGGING_ON do not set this

• [ ] Reduce build size by using the debian-slim PR

  • [ ] Maybe see what BUILD_REDUCE_IMAGE_SIZE does

• [ ] We'll also want to be able to upload all the target/ deb files to an apt repo.

  • [ ] And set proper Pinning so that packages cannot be upgraded to debian-ones.
  • [ ] Bonus if we have files that do not conflict (right now some packages have the same name AND VERSION as the upstream debian ones).

• [ ] We want to update the BCM packages to the latest version. This might be a separate task.

• [ ] We have some caching/mirror additions/changes that need to be upstreamed (or more easily configured locally).

  • [ ] Check that we have the stuff below covered for all cases.
  • [x] docker repo (exists as DEFAULT_CONTAINER_REGISTRY)
  • [ ] debian apt (half exists as MIRROR_URL)
  • [ ] pypi (needs patches)
  • [ ] rustlang downloads (unchecked)
  • [ ] golang downloads (unchecked)

• [ ] Check if we can access the REST API with the LIBYANG stuff.
