[openstack-dev] [nova] Hard fail if you try to rename an AZ with instances in it?

Sylvain has had a spec up for awhile [1] about solving an old issue 
where admins can rename an AZ (via host aggregate metadata changes) 
while it has instances in it, which likely results in at least user 
confusion, but probably other issues later if you try to move those 
instances, e.g. the request spec probably points at the original AZ name 
and if that's gone (renamed) the scheduler probably pukes (would need to 
test this).

Anyway, I'm wondering if anyone relies on this behavior, or if they 
consider it a bug that the API allows admins to do this? I tend to 
consider this a bug in the API, and should just be fixed without a 
microversion. In other words, you shouldn't have to opt out of broken 
behavior using microversions.
