osbuild CI tests, specifically image tests are not executing the test
script from osbuild-composer any more, but it uses manifest-db.
Therefore it is not needed to set up repository for osbuild-composer nor
install it.
Delete all unneeded lines from the script and replace them by installing
all osbuild packages needed to build images from `manifest-db`.

The default cache location for `osbuild-image-test` is actually
`/var/lib/osbuild/store`. Pass that to `osbuild` when setting
the `maximum cache size to set the size for the correct location.
Integrate the recently added file system cache `FsCache` into our
object store `ObjectStore`. NB: This changes the semantics of it:
previously a call to `ObjectStore.commit` resulted in the object
being in the cache (i/o errors aside). But `FsCache.store`, which
is now the backing store for objects, will only commit objects if
there is enough space left. Thus we cannot rely that objects are
present for reading after a call to `FsCache.store`. To cope with
this we now always copy the object into the cache, even for cases
where we previously moved it: for the case where commit is called
with `object_id` matching `Object.id`, which is the case for when
`commit` is called for last stage in the pipeline. We could keep
this optimization but then we would have to special case it and
not call `commit` for these cases but only after we exported all
objects; or in other words, after we are sure we will never read
from any committed object again. The extra complexity seems not
worth it for the little gain of the optimization.
Convert all the tests for the new semantic and also remove a lot
of them that make no sense under this new paradigm.
Add a new command line option `--cache-max-size` which will set
the maximum size of the cache, if specified.
On each PR test that osbuild don't break the image generation by testing
against the manifest-db that the produced image-infos are still the same
as the one stored.
OSTree tests, especially the fedora-ostree-image one, will soon
need the tight integration with the host for LVM2/LUKS support.
This we cannot run them in github action containers. Move them
to Schutzbot.
Explicitly install the new sub-package until composer gains the
needed requirement.
Previously:
We used images built from pre-mass-rebuild composes but installed packages
from post-mass-rebuild composes. This caused weird stuff like sshd crashing
when installing non-related packages via dnf.
Now:
Both the image and repositories are post-mass-rebuild ones. This should solve
these weird issues.
Let's explain how RPMs for RHEL are built:
We use a subscribed RHEL 8.x machine and mock build these on it. Mock
initializes its own buildroot based on the latest RHEL 8 CDN content, see[1].
This means that the minor version of the buildroot is independent of the minor
version of the host.
However, we currently upload RPMs to a directory whose name consists also of
the minor version of the host. Our hosts are currently running RHEL 8.3 so
the RPMs are uploaded into rhel-8.3 directory despite them being built in the
RHEL 8.4 buildroot (RHEL 8 CDN buildroot specifically). This means that
we cannot guarantee that they are installable on RHEL 8.3 which is weird.
This commit adds a special case for hosts that run on subscribed RHEL and
thus build RPMs in a buildroot constructed from RHEL CDN. These RPMs are
now uploaded into rhel-8-cdn directory. This change more accurately reflects
the way we build our RPMs and removes some confusion.
