I am confused about the plan for this in Folsom. I have seen by 
searching that multi_host in nova.conf and using Quantum is not 
supported in Essex, and that in Folsom there will be a Quantum way to 
get the same kind of ha as with multi_host. Does that mean that 
multi_host is being deprecated? At which milestone is Quantum scheduled 
to be "feature-complete"?
