      Previously, the approval process for a certificate signing request (CSR) failed because the node name and internal DNS entry for a CSR did not match the case-sensitive check. With this release, an update to the approval process for CSRs avoids the case-sensitive check and a CSR with a matching node name and internal DNS entry does not fail the matching-pair check.

      * Previously, the approval mechanism for certificate signing requests (CSRs) failed because the node name and internal DNS entry for a CSR did not match in terms of character case differences.

      Description of problem:

      Customer has a cluster in AWS that was born on an old OCP version (4.7) and was upgraded all the way through 4.15.
During the lifetime of the cluster they changed the DHCP option in AWS to "domain name". 
During the node provisioning during MachineSet scaling the Machine can successfully be created at the cloud provider but the Node is never added to the cluster. 
The CSR remain pending and do not get auto-approved

      Actual results:

         CSR don't get auto approved. New nodes have a different domain name when CSR is approved manually.

      Expected results:

          CSR should get approved automatically and domain name scheme should not change.
