Public bug reported:

This was found purely through code inspection, but the online data
migration to move aggregates to the nova API database has a problem
here:

https://github.com/openstack/nova/blob/a74d3ae4e815e3727961ef67bd801dada0267a0b/nova/objects/aggregate.py#L596

The problem is the AggregateNameExists exception message is translatable
and could be in unicode characters, and when casting that to str() in
python 2.7 it results in a UnicodeEncodeError:

Python 2.7.6 (default, Jun 22 2015, 18:00:18) 
[GCC 4.8.2] on linux2
Type "help", "copyright", "credits" or "license" for more information.
