Make HandleError prevent hot-loops

Add an error "handler" that just sleeps for a bit if errors happen more
often than 500ms. Manually tested against #39816. This doesn't fix #39816 but it does keep it from crippling a cluster.

```release-note
Prevent hotloops on error conditions, which could fill up the disk faster than log rotation can free space.
```
