--- upgrade: - | Modifies the default storage backend for Cloudkitty to InfluxDB, to match the default in Cloudkitty from Stein onwards. This is controlled via ``cloudkitty_storage_backend``. To use the previous default, set ``cloudkitty_storage_backend`` to ``sqlalchemy``. See `bug 1838641 <https://bugs.launchpad.net/kolla-ansible/+bug/1838641>`__ for details.
