Merge pull request #49812 from liggitt/local-up-node-authorizer 

Automatic merge from submit-queue

Enable node authorizer in local-up-cluster

Fixes #49822 

Enables the Node authorization mode to ensure the kubelet credential we create has permission to do kubelet-related things. Matches the default authorizers in gce/gke and CI clusters.

Related to the deprecation of the automatic binding of the `system:nodes` group to the `system:node` role on new deployments (https://github.com/kubernetes/kubernetes/pull/49638)

```release-note
`hack/local-up-cluster.sh` now enables the Node authorizer by default. Authorization modes can be overridden with the `AUTHORIZATION_MODE` environment variable, and the `ENABLE_RBAC` environment variable is no longer used.
```
