Move the FactsImageOptions from distro to the new rhsm/facts package.
At the same time define the values we use as an enum, including the
"test-manifest" value.
Though the values don't really matter, the test value is defined first
so it takes the 0 value, which feels nicer conceptually.
The field in the distro.ImageOptions is changed to be a pointer to allow
for nil values.
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.

ioutil has been deprecated since go 1.16, this fixes all of the
deprecated functions we are using:
ioutil.ReadFile -> os.ReadFile
ioutil.ReadAll -> io.ReadAll
ioutil.WriteFile -> os.WriteFile
ioutil.TempFile -> os.CreateTemp
ioutil.TempDir -> os.MkdirTemp
All of the above are a simple name change, the function arguments and
results are exactly the same as before.
ioutil.ReadDir -> os.ReadDir
now returns a os.DirEntry but the IsDir and Name functions work the
same. The difference is that the FileInfo must be retrieved with the
Info() function which can also return an error.
These were identified by running:
golangci-lint run --build-tags=integration ./...
The `/etc/rhsm/ca/redhat-uep.pem` CA is not valid for consumer
certificates.
As a result resolving the ostree ref should use the system's CA cert
pool.
The consumer key/cert is used to uniquely identify a system against a
candlepin instances. They're useful for any Red Hat (ostree) content
which requires (cert) authentication.
It turns out there are edge cases where the previous mechanism worked
and the new one doesn't. Employee subscription is one example, where the
key can be used to access basically any content, yet nothing it written
in the redhat.repo file. This should have no effect on hosts running
RHSM the usual way.
The problem: osbuild-composer used to have a rather uncomplete logic for
selecting client certificates and keys while fetching data from
repositories that use the "subscription model". In this scenario, every
repo requires the user to use a client-side TLS certificate. The problem
is that every repo can use its own CA and require a different pair of
a certificate and a key. This case wasn't handled at all in composer.
Furthermore, osbuild-composer can use remote workers which complicates
things even more.
Assumptions: The problem outlined above is hard to solve in the general
case, but Red Hat Subscription Manager places certain limitations on how
subscriptions might be used. For example, a subscription must be tight to
a host system, so there is no way to use such a repository in osbuild-composer
without it being available on the host system as well.
Also, if a user wishes to use a certain repository in osbuild-composer it
must be available on both hosts: the composer and the worker. It will come
with different pair of a client certificate and a key but otherwise, its
configuration remains the same.
The solution: Expect all the subscriptions to be registered in the
/etc/yum.repos.d/redhat.repo file. Read the mapping of URLs to certificates
and keys from there and use it. Don't change the manifest format and let
osbuild guess the appropriate subscription to use.
