Monitor and "bmc reset cold" the failed IPMIs

We observe that IPMIs stop pinging after a while. When the main OS
fails to respond on the same node, we get a bricked node that requires
physical intervention.

* Use arping -D, which is the simplest way of solving the "routing to
  192.168.10 subnet" concerns (as in, we don't have to care)
* End with /bin/false, so that such an event shows up as a "red" blip
