Kube scheduler uses legacy events API when bootstraping a new node

[alex-matei]

What happened?

Kube-scheduler doesn't have the ClusterRoleBinding needed when starting for the first time:

I0718 11:36:54.342302       1 round_trippers.go:466] curl -v -XGET  -H "Accept: application/vnd.kubernetes.protobuf, */*" -H "User-Agent: kube-scheduler/v1.24.2 (linux/amd64) kubernetes/f66044f/scheduler" 'https://172.31.14.173:6443/apis/events.k8s.io/v1'
I0718 11:36:54.342559       1 round_trippers.go:510] HTTP Trace: Dial to tcp:172.31.14.173:6443 succeed
I0718 11:36:54.353852       1 round_trippers.go:553] GET https://172.31.14.173:6443/apis/events.k8s.io/v1 403 Forbidden in 11 milliseconds

Because of this events.NewEventBroadcasterAdapter defaults to using the legacy API for reporting events.

What did you expect to happen?

Kube-scheduler should use the new events api.

How can we reproduce it (as minimally and precisely as possible)?

Use kubeadm to init a cluster made of a single master node. Create a pod and look at kubectl get events -o yaml for the scheduled events. EventTime field should be used instead of FirstTimestamp/LastTimestamp. If you restart kube-scheduler it will use the new API.

Anything else we need to know?

Kube scheduler is using the new event API but with a fallback mode, if events.k8s.io/v1beta1(I guess it's v1 now) is disabled, we'll use core/v1 Events then.
