Composition and Connections for Operators that create resources outside the cluster

One Operator pattern is where an Operator creates resources outside the cluster. An example is an Operator that provides Custom Resources to create resource in the cloud - Cloud VMs or S3 buckets etc. We should support 'kubectl composition' and 'kubectl connections' for such resources as well.

Start by reviewing the existing kubectl composition and kubectl connections behavior, then compare it with the operator pattern described for resources created outside the cluster. Done means defining and implementing support for discovering relationships involving external cloud resources such as VMs or S3 buckets.
