fix: use FQDN for horizon endpoints

The `public` and `internal` endpoints for `Horizon` have been set
explicitly to `kolla_external_fqdn` and `kolla_internal_fqdn` this
setup does not work if using `HAProxy` single frontend configuration and
can lead to `CORS` blocked when attempting to upload images via the
`Horizon` dashboard. This change brings `Horizon` configuration inline
with other services.
