new ReconcileResource based on the topology

[eguzki]

Base reconciler's ReconcileResource has been very helpful.

With the new approach based on a pre-computed topology, we should re-consider using it. That ReconcileResource performs a Get from the api server. The new agreed convention is to get this resource from the topology.

Today, it is being used at least in the consoleplugin reconciler

My vote: we keep using ReconcileResource. That brings update mutators. IMO, update mutators is a perfect match for operator reconciliation pattern.
