/kind feature

Right now, logcheck doesn't get released "properly" (no tag, no release notes). Kubernetes imports it via the commit hash (https://github.com/kubernetes/kubernetes/blob/0ade4678a7ba527d22f6baa81034dea423267608/hack/tools/go.mod#L14).

We could:

• tag it with hack/tools/v0.1.0
• move it to a separate repo
• do nothing and keep importing it via hash

Describe the solution you'd like

According to the discussion in kubernetes/kubernetes#108725 (comment), a separate repo seems more appropriate. There is no technical reason why the tool is in klog and releases are easier when it is a stand-alone repo.
