Description of problem:

When redeploying certs in a cluster, if the service-signer.crt is recreated due to expiring or other reasons, all secrets created based on this are no longer trusted.

Steps to Reproduce:
1.oc adm ca create-signer-cert --cert="/etc/origin/master/service-signer.crt" --key="/etc/origin/master/service-signer.key" --name="/etc/origin/master/openshift-service-serving-signer"   --serial=/etc/origin/master/service-signer.serial.txt --overwrite


Actual results:
OpenShift no longer trusts these certs. 

Expected results:
Either some controller checking and recreating secrets created from this or a `oc adm` command that can be called that would regenerate the secrets. 


Additional info:

Similar bugs via docs or installer that resolve this by manually asking user to recreate all secrets.
