🐛Fix behavior of rate limit option in priorityqueue.AddWithOpts

[zach593]

controller-runtime/pkg/controller/priorityqueue/priorityqueue.go

Lines 130 to 146 in 2e8ba92

	func (w *priorityqueue[T]) AddWithOpts(o AddOpts, items ...T) {
	w.lock.Lock()
	defer w.lock.Unlock()
	for _, key := range items {
	if o.RateLimited {
	after := w.rateLimiter.When(key)
	if o.After == 0 || after < o.After {
	o.After = after
	}
	}
	var readyAt *time.Time
	if o.After > 0 {
	readyAt = ptr.To(w.now().Add(o.After))
	w.metrics.retry()
	}

Since priorityqueue.AddWithOpts() allows adding multiple items, if o.RateLimited is true, the o.After value could get overwritten in the loop and affect subsequent items.

Hi @zach593. Thanks for your PR.

I'm waiting for a kubernetes-sigs member to verify that this patch is reasonable to test. If it is, they should reply with /ok-to-test on its own line. Until that is done, I will not automatically test new commits in this PR, but the usual testing commands by org members will still work. Regular contributors should join the org to skip this step.

Once the patch is verified, the new status will be reflected by the ok-to-test label.

I understand the commands that are listed here.
