keystoneclient 0.10.0 breaks django-openstack-auth unit tests completely

[Akihiro Motoki]

In keystoneclient 0.10.0, construct parameters in v2.0 UserManager/TenantManager was changed.

django-openstack-auth test data uses UserManager/TenantManager directly, so the unit tests no longer work.
To fix it, we need to add dummy parameters (None) to UserManager/TenantManager.

Note that this fix is not compatible with keystoneclient 0.9.0, but it cannot be avoided
because keystoneclient 0.10.0 change is not backward-compat.
The unit tests are run using the latest version of keystoneclient, so I think it can be accepted temporarily.

Once global requirements are updated to use keystoneclient >= 0.10.0 and django-openstack-auth requirements.txt is updated, the problem will be addressed.

global requirements update is now under review: https://review.openstack.org/#/c/108832/

    Replace UserManager/TenantManager with None in tests

    UserManager/TenantManager seems private classes in keystoneclient
    and the interface was changed in keystoneclient 0.10.0.
    django-openstack-auth tests actually don't need these managers,
    so this commit makes test data not use these classes.
