Bug Description

In case of N concurrent requests for volumes creation from one image, Cinder API creates N cache images.

While debugging resource leak in rally-cinder job, we discovered that we have a lot of cache volumes with equal names (image-<uuid>).

Simple rally scenario for reproduce:

Logs:
* unexpected resources (not created by rally directly)
