This issue updates #1986. This is intial, experimental implementation that will be updated with tests and edge cases prior to production 2.7.0 release. Teleport proxy adds support for Kubernetes API protocol. Auth server uses Kubernetes API to receive certificates issued by Kubernetes CA. Proxy intercepts and forwards API requests to the Kubernetes API server and captures live session traffic, making recordings available in the audit log. Tsh login now updates kubeconfig configuration to use Teleport as a proxy server.
