Allow the use of Cert-Manager to create certs for quay to use

[cmays20]

I can't find an easy way to use Cert-Manager as the secrets that it creates are of type kubernetes.io/tls and have keys of tls.key and tls.cert. Currently, the TLS config in the operator is looking for ssl.key and ssl.cert in the config-bundle-secret. Can this be altered or added to so that tls.key and tls.cert are supported?
