exec method

@override Future<DockerProcess?> exec(String containerName, String command, List<String> args, { bool? outputAsLines = true, int? outputLimit, OutputReadyFunction? stdoutReadyFunction, OutputReadyFunction? stderrReadyFunction, OutputReadyType? outputReadyType, })

Executes a command inside containerName with args.
