Install and configure controller node in cinder mentions auth_uri instead of www_authenticate_uri

[massimo.sgaravatto]

https://docs.openstack.org/cinder/rocky/install/cinder-controller-install-rdo.html

says that auth_uri must be set.

But in the log file there is this warning:

Deprecated: Option "auth_uri" from group "keystone_authtoken" is deprecated for removal (The auth_uri option is deprecated in favor of www_authenticate_uri and will be removed in the S release.). Its value may be silently ignored in the future.

    Remove auth_uri usage

    auth_uri in keystonemiddleware was deprecated and will be removed
    in Stein.

    This patch changed it to auth_url or www_authenticate_uri correctly

    Backporting to rocky as the option was deprecated there but our
    documentation was still instructing that it be set during installation.

    This modifies the cherry-pick to only bring back the documentation
    changes. Those should have been updated so deployers started using the
    preferred config option. Unfortunately, the doc changes were done along
    with code changes that would make existing configs incompatible.
    Following the documentation as it is now in the stable branch results in
    deprecation warnings in the logs.
