The current `NewRegistry` implementation allows for nil values in the
map, but this leads to subtle bugs when using the registry. This patch
enforces non-nil values by introducing additional checks before we
insert the value into the map.
The change unfortunately breaks a lot of tests and therefore it is
necessary to create additional mock: distro.
The new mock is used instead of the previous "real" implementation,
which used to contain nil values.
We must avoid depending on the host's state in any way. This achieves
isolation in the following ways:
- rather than the default config file /dev/null is used
- rather than sharing the host persistent state dir a temporary one
is used and thrown away for each call
- the module_platform_id is set explicitly per supported distro, rather
than taken from /etc/os-release.
Optionally, the cache directory can be configured, as we may want to keep
this separate from the host, if for no other reason than accounting.
However, the cache appears to be well-behaved, so we can keep sharing
it between calls (or even with the host). This speeds up things
considerably, so this is definitely what we want.

In our base distro definitions we exclude packages in addition to
including them. Extend dnf-json to support this, so we can depsolve
the base package set as well as the packages added in blueprints.

When support for osbuild result was added into osbuild-composer it was in
a bit hacky way - localtarget's location was reused as a path for the
result. This didn't make much sense because we want to store the result
even when image build has no localtarget.
Several past commits made store less dependant on the localtarget. The
responsibility for "holding the paths" to build artifacts was gradually
switched from the localtarget to the store while still maintaining
backwards compatibility - localtarget.Location still pointed at the
correct location.
This commit finishes the switch: local target now has no Location field.
The store is now fully responsible for managing the artifacts and paths
to them. LocalTarget is now just a simple "switch" - if image build has it,
then worker uploads an image into the store and it's then available for
download using the weldr API.
The compose now contains multiple image builds, but Weldr API does not
support this feature. Use the first image build every time.
Also start using the new types instead of plain strings.
We were using fedora-30 as a test-distro and tar as test-output, but
that causes lots of churn in the tests when we refactor things. Use
the test distro instead, when generic functionality is being tested
and restrict testing of the individual distros to the distro-specific
tests.

Introduce a DistroRegister object. For now this does not introduce
any functional changes, as the object is always instantited to be
the same. However, in follow-up patches it will get options.

dnf-json relies on dnf's ability to cache repository metadata. This is
important, because the API calls it quite often to serve requests for
package lists and depsolves.
However, osbuild's dnf stage always fetches new metadata, because it
doesn't have access to the host's cache. Since metadata is valid for
some time, even after a repository changed, the checksum we put in
the pipeline might be old.
Force a new metadata download when producing the pipeline. This is still
not perfect, but greatly reduces the probability of putting stale
metadata into the pipeline.
Instead of having a static repository checksum, set it dynamically from
the metadata that osbuild-composer last saw. This is implemented in
dnf-json, which returns the checksums for each repository on every call.
This enables the use of repositories that change over time, such as
fedora-updates. Note that the osbuild pipeline will break when such a
repository changes. This is intentional: pipelines have to be
reproducible.
This commit introduces basic support for upload API. Currently, all the routes
required by cockpit-composer are supported (except for /compose/log).
Also, ComposeEntry struct is moved outside of the store package. I decided
to do it because it isn't connected in any way to store, it's more connected
to API. Due to this move there's currently a known bug that image size is
not returned. This should be solved by moving Image struct inside Compose
struct by follow-up PR.
Make osbuild-composer use FromHost() directly. Everywhere else needs to
specify the distro explicitly.
Also don't panic when a distro doesn't exist. Instead, return nil. Make
sure all callers check for that.
Prior this commit there wasn't an easy to populate the store. The only way
was to call the weldr API or store methods. This design made testing of
various edges quite hard.
This commit adds store fixtures - an easy way how to define store state
before each test case.
In addition, the fixtures were refactored so that new instances are created
prior each test. Before this change the tests were in some cases dependant
on each other.
These endpoint are similar in many ways, therefore just one commit. Their
functionality is basically same as in lorax except for error messages and
weird edge cases when handling trailing slashes.

We want to test API methods which calls dnf. Unfortunately, calling dnf
is expensive operation - it requires network access and downloading
a lot of (meta)data. This commit changes the rpmmd implementation
so that it can be mocked.
