Watch list API endpoints prefixed with /watch are deprecated, models should start using list endpoint with watch=true

[oyvindio]

The watch list API endpoints prefixed with /watch are deprecated since Kubernetes 1.12. Watch operations should use the list API endpoints with a ?watch=true parameter. The k8s models that support watch list all use these deprecated endpoints. These should be changed to use the list endpoint with the watch parameter set. Maybe it makes sense to solve this via #55 ?
