db2555628c Fix: HPA suppresses FailedRescale event on successful conflict retry 
This change modifies the HPA controller to use retry.RetryOnConflict when updating a scale subresource. This prevents the controller from emitting a FailedRescale event on transient API conflicts if a subsequent retry succeeds. If the retry is successful, a SuccessfulRescale event is emitted. If all retries are exhausted and the conflict persists, the original FailedRescale event is emitted. This reduces event noise caused by race conditions where the scale subresource is updated by another process.

8a908e0c0b remove import doc comments 
The "// import <path>" comment has been superseded by Go modules.
We don't have to remove them, but doing so has some advantages:

- They are used inconsistently, which is confusing.
- We can then also remove the (currently broken) hack/update-vanity-imports.sh.
- Last but not least, it would be a first step towards avoiding the k8s.io domain.

This commit was generated with
   sed -i -e 's;^package \(.*\) // import.*;package \1;' $(git grep -l '^package.*// import' | grep -v 'vendor/')

Everything was included, except for
   package labels // import k8s.io/kubernetes/pkg/util/labels
because that package is marked as "read-only".

b01b016668 Use Go 1.21 min/max builtins 
The `min` and `max` builtins are available since Go 1.21[^1]. The
top-level go.mod file is specifying Go 1.22, so the builtins can be
used.

b584b87a94 kube-controller-manager: readjust log verbosity 
- Increase the global level for broadcaster's logging to 3 so that users can ignore event messages by lowering the logging level. It reduces information noise.
- Making sure the context is properly injected into the broadcaster, this will allow the -v flag value to be used also in that broadcaster, rather than the above global value.
- test: use cancellation from ktesting
- golangci-hints: checked error return value
