      Description

      libcloud crashs when accessing Swift based object store using Keystone auth API v3

      Code to reproduce:

      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')
      

      This produces the following stack trace:

      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
      

      Please see attached patch for a trivial fix. Using the 2.0 endpoint locator
      mechanism works fine with 3.x
