Client doesn't honor `tls-server-name` setting in kubeconfig

If a Kubernetes configuration file proposes the `tls-server-name` option, the asyncio client should configure the underlying HTTP library with this particular option.

See the upstream client issue about this: https://github.com/kubernetes-client/python/pull/1933
