resource crdbclusters/cockroachdb is missing the kubectl.kubernetes.io/last-applied-configuration annotation which is required by kubectl apply

After changing nodes from 3 to 5 and following the example in the README:

tobias@td:~/go/src/github.com/cockroachdb/cockroach$ minikube kubectl -- apply -f example.yaml 
Warning: resource crdbclusters/cockroachdb is missing the kubectl.kubernetes.io/last-applied-configuration annotation which is required by kubectl apply. kubectl apply should only be used on resources created declaratively by either kubectl create --save-config or kubectl apply. The missing annotation will be patched automatically.

@tbg , it appears this is likely related to minikube. We're not supporting that right now.
