Additional info:

In order to use the new flow introduced to fix this, create a CertificateRevocationRequest in the namespace of a HostedControlPlane as described in the test:

1. create a private key, certificate and certificate signing request using e.g. openssl
2. create admin credentials for the cluster by using a CertificateSigningRequest and {{CertificateSigningRequestApproval }}{{
   }}
3. revoke the break-glass signing certificate using the CertificateRevocationRequest
4. wait for the CRR status to show that it succeeded
5. ensure that the credentials created in step 2 are no longer valid
