this ^. use UUID please. you can google why auto increment is a probably 
not a good idea.

from a selfish pov, as gnocchi captures data on all resources in 
openstack, we store everything as a uuid anyways. even if your id 
doesn't clash in zun, it has a higher chance of clashing when you 
consider all the other resources from other services.
