exec auth support

[LeiYangGH]

My k8s cluster is in azure aks. I generate kube config using:

az login
az account set -s xxx
az aks get-credentials -g ggg -n nnn

It'll generate kube config like this:

• name: clusterUser_oc-k8s-app-1-dev-use2-aks_oc-k8s-app-1-dev-use2-aks
  user:
  auth-provider:
  config:
  access-token: sometoken
  apiserver-id: someguid
  client-id: someguid
  config-mode: "1"
  environment: AzurePublicCloud
  expires-in: "3907"
  expires-on: "1641893838"
  refresh-token: sometoken
  tenant-id: someguid
  name: azure

Then I can successfully use kubectl command.

But there is some very strange and annoying problem that asking me to login after a few minutes or hours randomly. similiar question

So I used kubelogin to solve this issue and works well.
The kube config is like this:

• name: clusterUser_oc-k8s-app-1-dev-use2-aks_oc-k8s-app-1-dev-use2-aks
  user:
  exec:
  apiVersion: client.authentication.k8s.io/v1beta1
  args:
  - get-token
  - --environment
  - AzurePublicCloud
  - --server-id
  - someguid
  - --client-id
  - someguid
  - --tenant-id
  - someguid
  command: kubelogin
  env: null
  provideClusterInfo: false

But kubernetes-client/csharp doesn't support this, apparently.

Is there any option in kubernetes-client/csharp that can achive the same purpose? i.e. get token before each request using the parameters in config and then use that token?

This is a definite gap in this library. I will work on the fix.

Is this issue already solve?Because when I try to use the kubelogin, the kubernetes-client/csharp still doesn't work with it
