We noticed internally that there are at least 3 implementations for
solving the task of pre-loading container images into isar-built base
systems, may it be that the images are not publicly available or the
device is only poorly connected, if at all. This series tries to solve
the task generically - hopefully.

This still needs at least documentation and CI hook-up, possibly more,
but I'd like to invite colleagues and the community in general to early
feedback.

BTW, patch 1 also introduces a fairly nice pattern to register a real
bitbake fetcher, rather than meddling with SRC_URI like we do for apt://
right now. Therefore, I'm planning to refactor the apt fetcher soon as
well, maybe even with progress reporting...

Jan Kiszka (3):
  Introduce fetcher from container registries
  container-loader: Introduce helper to load container images into local
    registry
  meta-isar: Add demo packages for installing prebuilt containers
