Currently, we are requiring that all versions in the compatibility requirement are present in the live CRD at CRD admission time.

There are fields to configure either AllServed or StorageOnly, as well as additionalVersions which will tweak which versions the admission should be caring about.

We need to update the logic to make sure we only compare the correct versions based on this configuration, and add integration tests to the suite that demonstrate this functionality.

Base functionality currently in https://github.com/openshift/cluster-capi-operator/pull/459
