keystoneclient expects an 'interface' keyword argument instead of 'endpoint_type'

[Paulo Matias]

This bug was originally reported to shade: https://storyboard.openstack.org/#!/story/2000762

After a failed attempt to fix it in shade side, Monty Taylor commented (see https://review.openstack.org/#/c/390992) that the issue was probably in os-client-config side.

What happens is that get_legacy_client constructs the keystone client passing an endpoint_type keyword argument which is simply ignored by the keystone client. It expects, instead, an interface argument (see https://github.com/openstack/python-keystoneclient/blob/f7c1d45a04bb2b024a985b8e30245d38f2bf8442/keystoneclient/httpclient.py#L253). As the interface argument is not passed, it always uses the default value ('admin'). This leads to the issues described in the original bug report.

The keystone client command line app is apparently not affected because it passes the interface keyword argument manually. However, scripts using shade or os-client-config directly may be affected, such as the os_project Ansible module.
