Does this PR introduce a user-facing change?

The in-tree azure plugin has been deprecated.  The https://github.com/Azure/kubelogin serves as an out-of-tree replacement via the kubectl/client-go credential plugin mechanism.  Users will now see a warning in the logs regarding this deprecation.

Additional documentation e.g., KEPs (Kubernetes Enhancement Proposals), usage docs, etc.:

Hi @sabbey37. Thanks for your PR.

I'm waiting for a kubernetes member to verify that this patch is reasonable to test. If it is, they should reply with /ok-to-test on its own line. Until that is done, I will not automatically test new commits in this PR, but the usual testing commands by org members will still work. Regular contributors should join the org to skip this step.

Once the patch is verified, the new status will be reflected by the ok-to-test label.

I understand the commands that are listed here.
