New upstream release. It contains features and bugfixes as well.

• Add image-container phase (lsedlar)

  This phase runs after image-build and osbuild and can embed an image into a container.

• pkgset: Add ability to wait for signed packages (lsedlar)

  If packages are appearing quickly in Koji, and signing them is triggered by automation, there may be a delay between the package being signed and compose running. In such case, it may be preferable to wait for the signed copy rather than fail the compose.

• pkgset: Include just one version of module (hlin)

  When adding extra modules via option pkgset_koji_module_builds, all other versions of the same stream potentially available in a Brew tag should be skipped.

• pkgset: Remove reuse file when packages are not signed (lsedlar)

  In such case, we never want to reuse the pkgset, as it risks leaking unsigned packages. The safest option is to remove the file completely.

• comps: Preserve default arg on groupid (lsedlar)

  When the wrapper processes comps file, it wasn't emitting "default" argument for groupid element. The default is false and most entries are actually using the default, so let's only emit it if set to true.

• Stop copying .git directory with module defaults (hlin)

  This will potentially speedup full cloning of big repositories.

• Drop usage of kobo.plugins (lsedlar)
