Use Case: Emergency Shutdown

The one place where the slides show Operations involved is in
emergency shutdown.  But there isn't much there, OMIS should flesh
that out.  I'd think we (OMIS) should make a more-than-one-slide
version of the Mini Use Case to explore it.

A number of questions arise.  What policies does the NOC use to decide
to shutdown?  What do they need to look at to get the evidence that
it's really a specific slice that's at fault?  What else needs to be
considered?  Does the NOC have any less drastic recourse?

What about handling other emergencies?  What if a compute cluster gets
turned into a botnet and unallocated slivers actually start to
misbehave?  If they aren't part of a slice there's no slice to
"emergency shutdown".  If the compute cluster is just cut off, you
penalize experiments that aren't misbehaving but just happen to have
slice resources there.
