- Don't set architecture, let Docker host decide it's own platform, remove `runtime` dependency and don't show default in `--help` - Remove most tests, we need to check only once if it works on different platform - Rename `DeleteImage` to `RemoveImage` to conform to existing function in `docker` cli, added options to specify `force` and `pruneChildren`
