swift-cli : a filter option(region_name) not working as expected

[Youngsol Koh]

swift --os-auth-url ${AUTH_URL}
      --auth-version 3
      --os-application-credential-id ${CLIENT_ID}
      --os-application-credential-secret ${CLIENT_SECRET}
      --os-region-name ${REGION}
      --os-auth-type v3applicationcredential auth

If you have multiple regions, the result of the cli is always pointing to last element in end-point list, regardless of the specified region(${REGION}). Thus, It will affect "download" command

swift version: python-swiftclient 3.13.0

Originated from this issue below.
https://bugs.launchpad.net/python-swiftclient/+bug/1506383

This problem is marked as commited but it is not working properly.

warnings.warn(
                'Providing attr without filter_value to get_urls() is '
                'deprecated as of the 1.7.0 release and may be removed in the '
                '2.0.0 release. Either both should be provided or neither '
                'should be provided.')

The commit forces put literal 'attr' to filter_kwarg though I think attr is attribute to filter.
Thus, literal 'attr' should be 'region_name' and corresponding filter value should be provided in the kwarg dict.
