ci-operator: expose ephemeral cluster versions based on parents

When we import a release from a stream that's configured to have a name
and be released in some way, we can piggy-back off of that name to
create a name for our release that clearly labels us as a derivative
while also uniquely identifying the test configuration that is running.
All of this is best-effort and will no-op if no release config is
present, allowing us to still mark the cluster version as one udner test
but not identifying the parent release.
