The cluster-olm-operator checks installed content for the maxOCPVersion property in order to mark the ClusterOperator as not upgradeable in certain cases. 

The current implementation is based on the Helm applier and looks the Helm secret for the property.

We need to:

• figure out where this metadata should go in the boxcutter/clusterextensionrevision implementation
• update cluster-olm-operator to check the installed content for the maxOCPVersion property
• update cluster-olm-operator to choose whether to use the helm or boxcutter implementation (or just use both...?)
