Upstream composer has introduce a few changes that we need to
adapt for:
- the koji composer API is now exposed on the standard https
port (443). Thus koji hub and web need to move to a different
pair: 8080 (http) and 4343 (https). Change the scripts and
tests for that
- the koji API gained a prefix 'api/composer-koji/v1/'. Change
client and unit tests to use that prefix. Use urljoin to
create new APIs
- composer configuration format (osbuild-composer.toml) has
changed and now also includes configuration for the CA
and allowed domains
- update the composer RPM repositories to the commit for the
21 upstream release.
Support connecting to koji via its fully qualified domain name, i.e.
org.osbuild.koji.koji. For this an extra SSL certificate is needed,
that has the FQDN as the subject, as well as a kerberos principal.
NB: This needs to have a apache VirtualHost section for the FQDN
that uses the new certificate as well.
