--- upgrade: - | Modifies the path for custom configuration of ``swift.conf`` from ``/etc/kolla/config/swift/<service>.conf`` to ``/etc/kolla/config/swift/<service>/swift.conf``, to avoid a collision with custom configuration for ``<service>.conf``. Here, ``<service>`` may be ``proxy-server``, ``account-*``, ``container-*`` or ``object-*``.
