* 合并devcontainer web相关的源文件，简化目录结构 * devcontainer、ssh_key_pair和devcontainer.cloud * fixed bug：创建容器时Host为localhost时创建失败的问题 * 删除了死代码，更新了一些命名（主要是去掉devstar字符串） * 常量名全大写 * devcontainer HOST改为用户设置的域名或IP * 安装时如没有配置devcontainer则默认设置为docker方式 * 直接使用kubernetes和docker简化代码提高可读性 * 去除services/devstar_devcontainer文件夹名中不必要的devstar字符串 * 去除services/devstar_devcontainer文件夹名中不必要的devstar字符串 * 文件名中去掉不必要的devstar字符串 * 变量名中删除不必要的Devstar字符串 * Merge branch 'dev' into feature-websshAndUpdateImage * change pages style * change Structure * fix bug * websshAndUpdateImage
