upgrade: use --ansi never for docker-compose (#1051)

Starting from `docker-compose` v1.28.0, the `--no-ansi` option is deprecated and a new, `--ansi never` option is introduced instead. This PR makes the deprecation warnings around this go away but bumps the minimum docker-compose version required to `1.28.0` as the older versions don't support the new option.
