- Implemented full support for contextual logging in  `client-go/rest`. `BackoffManagerWithContext` was used instead of  `BackoffManager` to ensure that the caller could interrupt the sleep. ([#127709](https://github.com/kubernetes/kubernetes/pull/127709), [@pohly](https://github.com/pohly)) [SIG API Machinery, Architecture,...

   verbosity at runtime for JSON output. ([#114609](https://github.com/kubernetes/kubernetes/pull/114609), [@pohly](https://github.com/pohly))

- Client-go/rest: contextual logging of request/response with accurate source code location of the caller ([#126999](https://github.com/kubernetes/kubernetes/pull/126999), [@pohly](https://github.com/pohly)) [SIG API Machinery and Instrumentation]

* Change GCP ILB firewall names to contain the "k8s-fw-" prefix like the rest of the firewall rules. This is needed for consistency and also for other components to identify the firewall rule as k8s/service-controller managed.

- Added the `WatchList` method to the `rest client` in `client-go`. When used,
  it establishes a stream to obtain a consistent snapshot of data from the server.

- Kube-controller-manager: the `--horizontal-pod-autoscaler-use-rest-clients` flag and Heapster support in the horizontal pod autoscaler, deprecated since 1.12, is removed. ([#90368](https://github.com/kubernetes/kubernetes/pull/90368), [@serathius](https://github.com/serathius))

* client-go: restores behavior of populating the BearerToken field in rest.Config objects constructed from kubeconfig files containing tokenFile config, or from in-cluster configuration. An additional BearerTokenFile field is now populated to enable constructed clients to periodically refresh tokens. ([#71713](https://gi...
