Convert some of the fields in the `RepoConfig` struct
to pointers. Since `RepoConfig` will be used to convert
custom repositories to an array of `osbuild.YumRepository`,
we need to ensure that fields that are not set explicitly
are not saved to the `/etc/yum.repos.d` repository files.
Update the internal RepoConfig object to
accept a slice of baseurls rather than a
single field. This change was needed to
align RepoConfig with the dnf spec [1].
Additionally, this change adds custom json
marshal and unmarshal functions to ensure
backwards compatibility with older workers.
Add json tags to the internal rpmmd config
since this is serialized in dnfjson.
Add unit tests to check the serialization
is okay.

is BYOS - bring your own subscription and requires registering in order
to access Red Hat content.

Extend the RepoConfig structure to contain new field ImageTypeTags.
Extend also other structures and functions as needed, to support loading
repository definitions, which use this new field. The idea is that a
repository should be used for building all image types, unless it has
some ImageTypeTags defined. In such case, it should be used only for
building the specific image types, which names are specified in the new
field.
Add RepoRegistry as a higher-level API to load and manage repository
definitions for each distribution. Currently it provides one method,
which returns a set of repositories needed to build a given image
type. The RepoRegistry uses the new ImageTypeTags field in the RepoConfig
structure and returns all the needed repositories for the image type.
Modify rpmmd unit tests and add unit tests for RepoRegistry.
Add News entry describing the change done to RepoConfig and its JSON
representation.

Separate the loading of repo definitions from JSON file from
`LoadRepositories()` to a standalone function
`loadRepositoriesFromFile()`, to make it easy to reuse it in the future.
Add unit tests for `LoadRepositories()` function.
Exclude github.com/osbuild/osbuild-composer/internal/rpmmd/test package
from test coverage. Package with just tests and no other code makes `go
test` to fail. This should be fixed in go 1.17.
