Description

Openshift MCO infuses pull secret info in every node's filesystem in the /var/lib/kubelet directory. In order for operator-controller to support using images hosted in private registries, it needs access to the pull secret information being stored by the MCO in the node it's running in.

The secret information needs to be host path mounted to the /etc/operator-controller directory for the controller's filesystem, so that the code in operator-controller (that uses an auth file if present in the /etc/operator-controller) directory (introduced in OPRUN-3555) can find the auth file, and use it for pulling bundle images. 

AC: 

openshift-operator-controller can install ClusterExtentions, the images for which are stored in private registries.
