Comment 2 for bug 1281896

> Warning: Scope(Class[Horizon]): keystone_host, keystone_port and keystone_scheme are deprecated. Use keystone_url instead.
> Warning: Scope(Class[Horizon]): keystone_host, keystone_port and keystone_scheme are ignored when keystone_url is set.

I'm going to hold off on addressing this until the following conversation is sorted out upstream...depending on the outcome here we may or may not need to compose the URI ourselves, or we may refactor how they're supplied/what they're supplied to.

We'll track this as a separate bug once consensus has been reached on the keystone parameter format.
