[micw523]

Link to the issue (please include a link to the specific documentation or example):
This is the non-critical part of #963

Description of the issue (please include outputs or screenshots if possible):
In k8s v1.16, a few old APIs got deprecated. See #966 and kubernetes/kubernetes#70672. Also see https://kubernetes.io/blog/2019/07/18/api-deprecations-in-1-16/
Need update:

• In examples/notebooks, the notebook create_deployment.ipynb uses apps/v1beta1 API.
• In examples/notebooks, the notebook intro_notebook.ipynb uses apps/v1beta1 API.

Could use an update:

• The example ingress_create.py uses networking/v1beta1 API. This could be upgraded to networking/v1 API.
