File: cinder/api/contrib/quotas.py line 19: the keystone client is imported from v3. So we cannot perform any calls through API v2.

Steps to reproduce:
1. Open in text editor /etc/cinder/cinder.conf:

2. Add the lines below:
[keymgr]
encryption_auth_url = http://localhost:5000/v2

3. Restart cinder services

4. Type 'cinder quota-show <tenant_id>'

5. The quotas API will return error code 500.
