Add the kustomize-hash-annotator kustomize plugin (#149)

* Add the kustomize-hash-annotator kustomize plugin

This adds the kustomize-hash-annotator [1] kustomize plugin to the
ArgoCD image. This plugin allows for dynamically annotating an object
with the hash of the contents of a configmap or secret, allowing for,
among other things, automatic rollouts of deployments based on updates
to configmaps and secrets.
