Hello Dear Operators,

OK, we've heard you loud and (mostly) clear. We won't remove the 
automated rescheduling behavior from Nova. While we will be removing the 
primary cause of reschedules (resource overconsumption races), we cannot 
yet eliminate the catchall exception handling on the compute node that 
triggers a retry of the instance launch. Nor will we be able to fully 
ameliorate the affinity/anti-affinity last-minute violation problems for 
at least another release.

So, we'll continue to support basic retries within the 
originally-selected cell.

Best,
-jay
