Diagnostic pulse can now be issued
A diagnostic pulse can now be issued on the IPMI interface using the fence_ipmilan agent. This new Technology Preview is used to force a kernel dump of a host if the host is configured to do so. Note that this feature is not a substitute for the `off` operation in a production cluster.

Proposed patch
Add option "diag" as new operation. On my machine I got:
Uhhuh. NMI received for unknown reason 31.
Do you have a strange power saving mode enabled?
Dazed and confused, but trying to continue
but machine is still up and running. I believe that signal was send correctly but my machine is not configured to support it.
@Gary: Does this patch do what you expect?

I'm still waiting for an explanation from them as to how exactly they've configured their hardware and the OS to make this function as they expect. However, they have confirmed that they've tested this functionality from the command line with fence_ipmilan and it works for them as expected.
