Add renovate config (#20)

* extract image references to top-level kustomize

Move the strict definition of images from the deployment manifests for
each proxy type to their respective kustomize.yaml.  This lets us watch
for updates on them using renovate.

* add renovate config

This enables updates for the following:
- go.mod dependencies
- images referenced in container manifests
- images referenced in kustomize manifests
