[yocto-autobuilder2,v3,0/6] Implement 'containers' jobs

From: Tim Orling <tim.orling@konsulko.com>

This series builds on top of the patches already merged from v2.

This series contains the 'yocto-autobuilder-helper' patches to enable:
* building, testing and publishing of 'vcontainer-tarball'
  - vcontainer-tests job
* building and pushing containers from:
  - meta-virtualization
* containers are pushed when the push_containers boolean is set in the
  AutoBuilder UI
  - regstries are set with CONTAINER_REGISTRIES variable
* authentication uses local user credentials (e.g. ~/.docker/config.json
  or .../auth.json for podman)
* containers are tagged with PV_MAJOR, PV_MAJOR.PV_MINOR, DISTRO_CODENAME
  and yocto-x.y release (yocto-x.y.z for release builds).

Additional features, such as container signing and attaching SLSA provenance
attestations will come in a future series, once this initial functionality
is agreed upon an stable.

Concerns about the possible infinite loop around the tarball extraction
"while True, try, expect OSError" code [1] are addressed separately [2],
since the original patch has been merged.

This series relies on the resolution of [3] and [4].

Changes in v2:
* Simplify by  merging vdkr-tests and vpdmn-tests into vcontainer-tests
* Simplify by building containers from meta-virtualization:
- Depends on resolution of: https://lists.yoctoproject.org/g/meta-virtualization/message/9826
* Workaround for recent (since Friday May 29, 2026) errors:
  Error: reading blob sha256:<hash>: file integrity checksum failed for "<file>"
  - This is probably related to either sstate changes or recent changes in vcontainer-common...

Changes in v3:
* vcontainer-tarball is installed in jobs that set "vcontainer" similar to "extratools", instead
  of the more global "buildtools" behavior.
* The (rather large amount of) code for pushing containers in run-config is broken out into
  a dedicated run-push-containers script.
* Workaround for pushing containers is moved to run-push-containers. The most recent
  behavior (on top of meta-virt master-next) showed a different error pattern:
  Error: reading blob sha256:<hash>: EOF
  The workaround simply removes all container images from the VM's container-registry before
  importing or pushing new container images. The commit message was reworded accordingly.
* Rather than installing latest versions of pip, setuptools and wheel, silence the pip
  warning with PIP_DISABLE_PIP_VERSION_CHECK=1
* Rather than installing the latest versions of pytest, pytest-timeout and pexpect, install
  from meta-virtualization/tests/requirements.txt (pending).
* Refactor run-vcontainer-tests script to use optargs instead of a mix of positional args
  and env vars.
