The auth_uri option was deprecated and renamed in Queens:
I0cf11da3d395749df28077427689fdafc8a6b981
The auth_uri option is also no longer necessary, at least
for the purpose of the nova install guide, since all identity
service requests can be served through the single auth_url.
This change removes auth_uri usage and also updates the
auth_url value to match what is in the keystone install
guide:
