webhook-create-signed-cert.sh create a certificate that is valid for only 65 days. After 65 days, Openshift cannot launch any new build. The cert must be deleted and recreated then the quay-bridge operator must be uninstalled and reinstalled.

To check the validity of the certs :
1. oc get secret quay-bridge-operator-webhook-certs -n openshift-operators -o yaml
2. Decode the certificate from the yaml, which is in base64 (certs.pem: ) with
[https://www.base64decode.org/
]
3. Copy the result in a file, cert.pem
4. openssl x509 -in cert.pem -text -noout
Validity
Not Before: Aug 27 12:43:04 2020 GMT
Not After : Sep 19 12:29:41 2020 GMT

Expected results:
1. we should be able to pass a period as an argument to the webhook-create-signed-cert.sh
2. Openshit must report that this certificate has expired and must be replaced
