Support Operator Lifecycle Manager (OLM) registry+v1 bundles

Describe the problem/challenge you have
The Operator Lifecycle Manager (OLM) is a project that aims to simplify lifecycle management of Kubernetes-native applications ("operators") and provide additional guardrails to prevent actions that can unintentionally or accidentally result in misconfigurations or data loss.

There is a large collection of operators that work with OLM. Many are viewable at https://operatorhub.io. OLM has a custom packaging format called registry+v1 that is an OCI image with a specific directory layout that OLM expects.

We are currently investigating using parts of the Carvel suite in our next major version of OLM, "v1", currently in development. kapp-controller is of particular interest. We'd like to use it to manage the content OLM applies to clusters, but kapp-controller doesn't currently support OLM's registry+v1 format.

Describe the solution you'd like
Add support for OLM's registry+v1 format as a "templating" step. This would take the contents of a .spec.fetch.image that points at an OLM registry+v1 image and process them in such a way that the .spec.deploy.kapp step can apply them to the cluster correctly.

Anything else you would like to add:
