Status check should monitor CRDs to ensure they are established

Our status checks should [wait for CRDs to be established](https://kubernetes.io/docs/tasks/extend-kubernetes/custom-resources/custom-resource-definitions/). This should be checking that the `status.conditions[type="Established"].status == "True"`. Valid condition names are `Established`, `NamesAccepted`, and `Terminating` (via `kubectl explain crd.status.conditions.type`).

```
