Motivation

There is currently no way to access the namespace: Option<String> private field of the Api instance. In case the Api is passed around code, as a developer of a kube-rs operator / controller, I want to be able to verify the namespace scope of the Api instance.

Further details in Feature Request: #1787

Solution

Provide immutable access to the namespace: Option<String> private field as a Deref.
