* Delete custom cache setup, no longer necessary * Consolidate client usage and use dynamic discovery (see kubernetes-sigs/controller-runtime#321 — hat tip to @danwinship for openshift/cluster-network-operator#95). Fixes [bz1711373](https://bugzilla.redhat.com/show_bug.cgi?id=1711373). * Plumb the cache through for future use

controller-manager assumes that all resource Kinds will have been created before it starts up, so it can't deal with the case of creating a CRD and then creating an instance of that CRD (or waiting for another operator to create a CRD, and then creating an instance of that CRD). This is maybe not the bestest fix, but it works and we can discuss it further upstream.
Note that this code would be especially bad/inefficient if we thought that the controller was going to be repeatedly asked about objects of non-existent types, but there's no reason that would happen in CNO, so the reload path should only get hit in the creating-an-instance-of-a-previously-created-CRD case.
