This patch enables users to override WEBSSO_KEYSTONE_URL variable for
Horizon.
As per docs:
> Use this when OPENSTACK_KEYSTONE_URL is set to an internal Keystone
endpoint and is not reachable from the external network where the
identity provider lives. This URL will take precedence over
OPENSTACK_KEYSTONE_URL if the login choice is an external identity
provider (IdP).
