In addition to the required base layer, provided via the the input
of the same name, the oci-archive stage now accepts up to nine
additional layers that get added on top of each other, sorted in
ascending order, i.e. `layer.1` to `layer.9`.
Adapt the `fedora-ostree-container` example manifest so that the
ostree commit is now in a separate layer, which makes it possible
to share the base layer between different commits container.
Change the test manifests that use containers to not include
docs when installing. Also don't install docs in the build root
for those manifests. Since the fedora-ostree-container.mpp is
being built in CI, this also tests that the new option.
The `org.osbuild.files` source provides files, but might in the
future not be the only one that does. Therefore rename it to
match the internal tool that is being used to fetch the files.
This is done for most other osbuild modules that target tools.
The format v1 loader is adapted to make this change transparent
for users of the v1 format, so we are backwards compatible.
Change the MPP depsolve preprocessor so that for format v2 based
manifest `org.osbuild.curl` source is used. Also rename the
corresponding source test. Adapt the format v2 mod test to use
the curl source.
Add a v2 manifest to builds an ostree commit, then builds a small
container with a webserver and puts that commit into it.
Start a new test suit where this manifest is built and then checked
that the artifact exists. In the future the artifact should also be
inspected and run by a container engine and the commit be pulled
via ostree.
