As part of the work of wg-manifests for 1.3
(https://github.com/kubeflow/manifests/issues/1735), we are moving manifests
development in upstream repos. This gives the application developers full
ownership of their manifests, tracked in a single place.
This commit copies the manifests for application `Notebook Controller`
from path `apps/jupyter/notebook-controller/upstream` of kubeflow/manifests to path
`components/notebook-controller/config` of the upstream repo (https://github.com/kubeflow/kubeflow).
