Issue description

I think it would be better if the exercise is augmented to explain how the quay instance can be made persistent by using an OBC provided by ODF.

This is the link that describes how to do that:
https://docs.redhat.com/en/documentation/red_hat_quay/3.14/html-single/deploying_the_red_hat_quay_operator_on_openshift_container_platform/index#noobaa-unmanaged-storage-example

We would like to have our images persistent, not in ephemeral storage.
