Kustomize plugin

Hi,

We are using sealed-secrets together with kustomize and it's a bit of pain to handle it for multiple environments right now, since you need a new name of the sealed-secret to trigger the rolling-upgrade of services. I saw that kustomize now supports plugin, would be great if some kind soul could create a plugin for sealed-secrets :) Prbly a lot of people would appreciate it.
