it is not possible to prune all volumes using `docker system prune`, the best that can be done is the removal of anonymous volumes using the `--volumes` flag https://docs.docker.com/reference/cli/docker/system/prune/#description add new option `autoPrune.allVolumes.enable` which runs `docker volume prune --all --force` when the system prune service runs. https://docs.docker.com/reference/cli/docker/volume/prune/ add new test for this feature, and the autoPrune feature
