Description of your changes

Example:

func Reconcile(...) (reconcile.Result, error) {
    ...

    return errors.SilentlyRequeueOnConflict(reconcile.Result{}, r.hcClient.Patch(ctx, obj, client.MergeFrom(orig)))
}

If the returned error is a (possibly wrapped) Kube conflict error, it is dropped (replaced with nil) and the result is replaced with an immediate requeue.

This way, the conflict errors, which are part of the Kube's optimistic concurrency protocol and not actual errors, do not show up as ugly backtrace in the logs.

Alternative way to use:

errors.WithSilentRequeueOnConflict(NewReconciler())
