centos7 安装 docker-compose

The new Compose V2, which supports the compose command as part of the Docker CLI, is now available.Compose V2 integrates compose functions into the Docker platform, continuing to support most of the previous docker-compose features and flags. You can test the Compose V2 by simply replacing the dash (-) with a space, and by running docker compose, instead of docker-compose.

新的 Compose V2 支持将 compose 命令作为 Docker CLI 的一部分，现已推出。Compose V2 将 compose 功能集成到 Docker 平台中，继续支持之前的大部分 docker-compose 功能和标志。您可以通过简单地将破折号 (-) 替换为空格并运行 docker compose 而不是 docker-compose 来测试 Compose V2。

也就是新的 compose 被集成到了 docker cli 里。
