What happened (please include outputs or screenshots):
Kubernetes API response:

Response is not chunked. Header 'transfer-encoding: chunked' is missing.

What you expected to happen:
Python client should add transfer-encoding header, when allow_watch_bookmarks is True https://kubernetes.io/docs/reference/using-api/api-concepts/#watch-bookmarks

How to reproduce it (as minimally and precisely as possible):
Run watcher for any object list.
