A lot here, but this LGTM. I see that we change how the replacement logic works to allow for pulling from Vault mid-replacement in the case of placeholders containing specific Vault paths. I also see that we pass the annotations along to GetSecrets to act on them there, and that we use unstructured.Unstructured from the very beginning to make it easy to make proper k8s resources and serialize back to YAML.
