This updates the Kustomize dependency for airshipctl to api/v0.3.1, which is the oldest version which will support the Replacement Transformer plugin. Some changes were needed to accomodate the fact that various apis that airshipctl was relying on were moved to kustomize-insternal packages, namely: - Integrated with the krusty.Kustomizer to drive kustomization - Removed the custom plugin loader which leveraged the Unknown type - Worked around NoFieldError becoming private, inc. removing a test As a follow on we'll need to re-integrate plugin functionality somehow. Also, in this release Kustomize has implemented support for the "config.kubernetes.io/local-config" annotation, which we'd planned to use to to avoid deploying some documents to the Kubernetes API. It turns out the semantics are different than we anticipated; Kustomize also fails to return these docs via document *selection*. Therefore, this change reverts to an earlier approach which uses a custom airshipit.org/deploy-k8s label. Change-Id: I7022e12464ea7b6a3ca8609f99f3699bf8da0edd
