FutureWarning: '...' is an invalid UUID for user_ids

[Peter Nordquist]

Akin to this bug on Gnocchi https://bugs.launchpad.net/gnocchi/+bug/1505984, Cinder is using UUIDs for user_ids and they can be user defined strings. In our case, Keystone is attached to LDAP and the user_id is a 64 character string of numbers and letters. I've only seen the warning so far so I'm not sure if I will run into issues with creating or using volumes.

Here's an example warning FutureWarning: '<a user id>' is an invalid UUID. Using UUIDFields with invalid UUIDs is no longer supported, and will be removed in a future release. Please update your code to input valid UUIDs or accept ValueErrors for invalid UUIDs. See http://docs.openstack.org/developer/oslo.versionedobjects/api/fields.html#oslo_versionedobjects.fields.UUIDField for further details
