Description of problem:

We did breaking api changes in this issue: https://issues.redhat.com/browse/ACM-25560

We did not anticipate that installer installs all CRDs automatically. So now, even without fine grained rbac enabled, this will cause issues during ACM 2.15 to 2.16 upgrades:

MCH status:

message: 'Error installing CRDs: CustomResourceDefinition.apiextensions.k8s.io
        "multiclusterroleassignments.rbac.open-cluster-management.io" is invalid:
        status.storedVersions[0]: Invalid value: "v1alpha1": missing from spec.versions;
        v1alpha1 was previously a storage version, and must remain in spec.versions
        until a storage migration ensures no data remains persisted in v1alpha1 and
        removes v1alpha1 from status.storedVersions' 

Version-Release number of selected component (if applicable):

How reproducible: every time (assuming)

Steps to Reproduce:

1. Install acm 2.15
2. Upgrade to 2.16

Actual results:

Upgrade blocked, error in MCH

Expected results:

Upgrade is successful; upgrades CRD api version successfully.
