- Use opendev.org/airship/airshipctl/pkg/document.Selector instead of sigs.k8s.io/kustomize/api/types.Selector which makes selectors conversion code unnecessary - Use document.GetSecretDataKey instead of document.DecodeSecretData which removes code duplicates Change-Id: Ie2c6b8d8222b7acb1b657f8d786a8c3a06b0c6fd
