At the moment it is very difficult to pull images from a private registry that hasn't been configured on Kubernetes nodes as there is no way to specify imagePullSecrets on pods. This change introduces a snippet that can return a set of image pull secrets using either a default or a per pod value. It also adds this new snippet to the manifests for standard job types.
