Add a cluster's proxy url when loading from config file

[joewesch]

Here is a mock example of my .kube/config file:

apiVersion: v1
clusters:
- cluster:
    server: https://192.0.2.100
    proxy-url: http://192.0.2.103:3128
  name: mock
contexts:
- context:
    cluster: mock
    user: none
  name: mock
current-context: mock
kind: Config
users:
- name: none
  user: {}

Can you please add the ability to read the cluster's proxy-url setting and add it to the client configuration?

Hi @tomplus,
I’ve implemented a fix to support proxy-url in kubeconfig cluster definitions and added details on how I verified the behavior manually (using a local HTTP proxy to confirm requests are routed through it).
Could you please take a look and let me know if the approach and verification look okay to you, or if you’d like any changes?
