OK I guess we should make this a side discussion at some point, or hit 
me up in IRC, but if you're requesting networks='none' with microversion 
 >= 2.37 then nova should not allocate any networking, it should not 
event attempt to do so.

Maybe the issue is the server is created with networks='auto' and has a 
port, and then when you 'update the stack' it doesn't delete that server 
and create a new one, but it tries to do something with the same server, 
and in this case you'd have to detach the port(s) that were previously 

I don't know how Heat works, but if that's the case, then yeah that 
doesn't sound fun, but I think Nova provides the APIs to be able to do this.
