> libcloud crashs when accessing Swift based object store using Keystone auth API v3
> Code to reproduce:
> {code}
> from libcloud.storage.types import Provider
> from libcloud.storage.providers import get_driver
> cls = get_driver(Provider.OPENSTACK_SWIFT)
> driver = cls('USER', 'PASSWORD', ex_force_auth_version='3.x_password',  ex_force_auth_url='https://keystone.cst.de:5001',
> ex_tenant_name='signing_service', ex_domain_name='AD', ex_force_service_name='ceph')
> container = driver.create_container(container_name='fnord')
> {code}
> This produces the following stack trace:
> {code}
> Traceback (most recent call last):

>   File "C:\Python27\lib\site-packages\libcloud\storage\drivers\cloudfiles.py", line 141, in get_endpoint
>     if endpoint:
> UnboundLocalError: local variable 'endpoint' referenced before assignment
> {code}
> Please see attached patch for a trivial fix. Using the 2.0 endpoint locator
> mechanism works fine with 3.x
