> We should be able to detect and monitor the failure rate of workers on nodes,
> and come up with a few different probabilities. How likely is it that this
> worker will fail on this particular node in the next n mins. How likely is
> it that all workers will fail on this particular node in the next n mins.
> How likely is it that this worker will fail on any node in the next n mins.
> With these we should be able to detect bad nodes and blacklist them, and
> ideally trigger external systems that can take actions to try and fix the
> nodes. We should also be able to detect topologies that have bugs in the
> common case warn them, and in the worst case stop trying to run them.
