Describe the feature request

There are ~165 manifests in the repo using deprecated versions of DaemonSets, Deployments, ReplicaSets, and StatefulSets (in extensions/v1beta1, apps/v1beta1, or apps/v1beta2).

These resources have been deprecated since k8s v1.9 and are planned to no longer be served starting in k8s v1.16 (c.f. kubernetes/kubernetes#43214).

All supported versions of k8s have the apps/v1 versions of these resources available. Switching manifests to use the GA versions of these resources ensures broader compatibility and longer-term support.

Migration involves:

• changing apiVersion to apps/v1
• populating spec.selector.matchLabels with the contents of spec.template.metadata.labels if spec.selector does not already exist
• populating metadata.labels with the contents of spec.template.metadata.labels if metadata.labels does not already exist
