Completes #67192.

This PR adds a secure port 10259 to the scheduler

  • enabled by default as for the controller manager
  • deprecates the old insecure port
  • adds exhaustive delegated authn/z tests.
Add secure port 10259 to the kube-scheduler (enabled by default) and deprecate old insecure port 10251. Without further flags self-signed certs are created on startup in memory.

Fixes #58983.

deprecates the old insecure port

@sttts I want to learn about the motivations behind deprecating the plain http (insecure!?) port. Can you point me to any related discussions about this?

in addition to tolerating missing kubeconfig, this needed to tolerate forbidden failures in lookupMissingConfigInCluster... nothing granted the scheduler delegated authentication permissions by default
