Merge pull request #6031 from abutcher/temporary-servinginfo-clientca

Automatic merge from submit-queue.

Temporarily set master servingInfo.clientCA as client-ca-bundle.crt during rolling CA redeployment.

This PR temporarily configures master `servingInfo.clientCA` as `client-ca-bundle.crt` during CA redeploy so that clients referencing the old OpenShift CA can continue to function until all cluster certificates have been replaced and `servingInfo.clientCA` is reset to `ca.crt`.

`client-ca-bundle.crt` is a new bundle created by the `openshift_ca` role which contains old and new OpenShift CA certificates.
